TIMEOUT
This field specifies a number of peripheral group (clk_group) clock cycles. If an AHB-Lite bus transfer takes more than the specified number of cycles (timeout detection), the bus transfer is terminated with an AHB-Lite bus error and a fault is generated (and possibly recorded in the fault report structure(s)).
'0x0000'-'0xfffe': Number of peripheral group clock cycles.
'0xffff': This value is the default/reset value and specifies that no timeout detection is performed: a bus transfer will never be terminated and a fault will never be generated.

DIV_SEL
(TYPE_SEL, DIV_SEL) specifies the divider on which the command (DISABLE/ENABLE) is performed.
If DIV_SEL is '63' and TYPE_SEL is '3' (default/reset value), no divider is specified and no clock signal(s) are generated.
[5:0]
read-write
TYPE_SEL
Specifies the divider type of the divider on which the command is performed:
0: 8.0 (integer) clock dividers.
1: 16.0 (integer) clock dividers.
2: 16.5 (fractional) clock dividers.
3: 24.5 (fractional) clock dividers.
[7:6]
read-write
PA_DIV_SEL
(PA_TYPE_SEL, PA_DIV_SEL) specifies the divider to which phase alignment is performed for the clock enable command. Any enabled divider can be used as reference. This allows all dividers to be aligned with each other, even when they are enabled at different times.
If PA_DIV_SEL is '63' and PA_TYPE_SEL is '3', 'clk_peri' is used as reference.
[13:8]
read-write
PA_TYPE_SEL
Specifies the divider type of the divider to which phase alignment is performed for the clock enable command:
0: 8.0 (integer) clock dividers.
1: 16.0 (integer) clock dividers.
2: 16.5 (fractional) clock dividers.
3: 24.5 (fractional) clock dividers.
[15:14]
read-write
DISABLE
Clock divider disable command (mutually exclusive with ENABLE). SW sets this field to '1' and HW sets this field to '0'.
The DIV_SEL and TYPE_SEL fields specify which divider is to be disabled.
The HW sets the DISABLE field to '0' immediately and the HW sets the DIV_XXX_CTL.EN field of the divider to '0' immediately.
[30:30]
read-write
ENABLE
Clock divider enable command (mutually exclusive with DISABLE). Typically, SW sets this field to '1' to enable a divider and HW sets this field to '0' to indicate that divider enabling has completed. When a divider is enabled, its integer and fractional (if present) counters are initialized to '0'. If a divider is to be re-enabled using different integer and fractional divider values, the SW should follow these steps:
0: Disable the divider using the DIV_CMD.DISABLE field.
1: Configure the divider's DIV_XXX_CTL register.
2: Enable the divider using the DIV_CMD_ENABLE field.
The DIV_SEL and TYPE_SEL fields specify which divider is to be enabled. The enabled divider may be phase aligned to either 'clk_peri' (typical usage) or to ANY enabled divider.
The PA_DIV_SEL and PA_TYPE_SEL fields specify the reference divider.
The HW sets the ENABLE field to '0' when the enabling is performed and the HW set the DIV_XXX_CTL.EN field of the divider to '1' when the enabling is performed. Note that enabling with phase alignment to a low frequency divider takes time. E.g. To align to a divider that generates a clock of 'clk_peri'/n (with n being the integer divider value INT_DIV+1), up to n cycles may be required to perform alignment. Phase alignment to 'clk_peri' takes affect immediately. SW can set this field to '0' during phase alignment to abort the enabling process.

DIV_SEL
Specifies one of the dividers of the divider type specified by TYPE_SEL.
If DIV_SEL is '63' and TYPE_SEL is '3' (default/reset value), no divider is specified and no clock control signal(s) are generated.
When transitioning a clock between two out-of-phase dividers, spurious clock control signals may be generated for one 'clk_peri' cycle during this transition. These clock control signals may cause a single clock period that is smaller than any of the two divider periods. To prevent these spurious clock signals, the clock multiplexer can be disconnected (DIV_SEL is '63' and TYPE_SEL is '3') for a transition time that is larger than the smaller of the two divider periods.

COUNT
Amount of 'clk_peri' cycles a specific trigger is activated. During activation (ACTIVATE is '1'), HW decrements this field to '0' using a cycle counter. During activation, SW should not modify this register field. A value of 255 is a special case: HW does NOT decrement this field to '0' and trigger activation is under direct control of ACTIVATE when ACTIVATE is '1' the trigger is activated and when ACTIVATE is '0' the trigger is deactivated.
[23:16]
read-write
OUT_SEL
Specifies whether trigger activation is for a specific input or ouput trigger of the trigger multiplexer. Activation of a specific input trigger, will result in activation of all output triggers that have the specific input trigger selected through their TR_OUT_CTL.TR_SEL field. Activation of a specific output trigger, will result in activation of the specified TR_SEL output trigger only.
'0': TR_SEL selection and trigger activation is for an input trigger to the trigger multiplexer.
'1': TR_SEL selection and trigger activation is for an output trigger from the trigger multiplexer.

SUBREGION_DISABLE
This field is used to individually disabled the eight equally sized subregions in which a region is partitioned. Subregion disable:
Bit 0: subregion 0 disable.
Bit 1: subregion 1 disable.

Bit 3: subregion 3 disable.
Bit 4: subregion 4 disable.
Bit 5: subregion 5 disable.
Bit 6: subregion 6 disable.

E.g., a 64 KByte address region (REGION_SIZE is '15') has eight 8 KByte subregions. The access control as defined by PPU_REGION_ATT applies if the bus transfer address is within the address region AND the addressed subregion is NOT disabled. Note that the smallest region size is 256 B and the smallest subregion size is 32 B.

ADDR24
This field specifies the most significant bits of the 32-bit address of an address region. The region size is defined by PPU_REGION_ATT.REGION_SIZE. A region of n Byte is always n Byte aligned.

SLV_STALL
Processor debug access control:
'0': Access.
'1': Stall access.
This field is used to stall/delay debug accesses. This is useful to protect execution of code that needs to be protected from debug accesses.
[0:0]
read-write
ENABLED
Processor enable:
'0': Disabled. Processor clock is turned off and reset is activated. After SW clears this field to '0', HW automatically sets this field to '1'. This effectively results in a CM0+ reset, followed by a CM0+ warm boot.
'1': Enabled.
Note: The intent is that this bit is modified only through an external probe or by the CM4 while the CM0+ is in Sleep or DeepSleep power mode. If this field is cleared to '0' by the CM0+ itself, it should be done under controlled conditions (such that undesirable side effects can be prevented).
Note: The CM0+ CPU has a AIRCR.SYSRESETREQ register field that allows the CM0+ to reset the complete device (ENABLED only disables/enables the CM0+), resulting in a warm boot. This CPU register field has similar 'built-in protection' as this CM0_CTL register to prevent accidental system writes (the upper 16-bits of the register need to be written with a 0x05fa key value; see CPU user manual for more details).

SLOW_INT_DIV
Specifies the slow clock divider (from the peripheral clock 'clk_peri' to the slow clock 'clk_slow'). Integer division by (1+SLOW_INT_DIV). Allows for integer divisions in the range [1, 256] (SLOW_INT_DIV is in the range [0, 255]).
Note that this field is retained. However, the counter that is used to implement the division is not and will be initialized by HW to '0' when transitioning from DeepSleep to Active power mode.
[15:8]
read-write
PERI_INT_DIV
Specifies the peripheral clock divider (from the high frequency clock 'clk_hf' to the peripheral clock 'clk_peri'). Integer division by (1+PERI_INT_DIV). Allows for integer divisions in the range [1, 256] (PERI_INT_DIV is in the range [0, 255]).
Note that this field is retained. However, the counter that is used to implement the division is not and will be initialized by HW to '0' when transitioning from DeepSleep to Active power mode.
Note that Fperi <= Fperi_max. Fperi_max is likely to be smaller than Fhf_max. In other words, if Fhf = Fhf_max, PERI_INT_DIV should not be set to '0'.

PRIO
Device wide bus arbitration priority setting ('0': highest priority, '3': lowest priority).
Notes:
The AHB-Lite interconnect performs arbitration on the individual beats/transfers of a burst (this optimizes latency over locality/bandwidth).
The AXI-Lite interconnects performs a single arbitration for the complete burst (this optimizes locality/bandwidth over latency).
Masters with the same priority setting form a 'priority group'. Within a 'priority group', roundrobin arbitration is performed.

PC_MASK_0
Protection context mask for protection context '0'. This field is a constant '0':
- PC_MASK_0 is '0': MPU MS_CTL.PC[3:0] can NOT be set to '0' and PC[3:0] is not changed. If the protection context of the write transfer is '0', protection is not applied and PC[3:0] can be changed.
[16:16]
read-only
PC_MASK_15_TO_1
Protection context mask for protection contexts '15' downto '1'. Bit PC_MASK_15_TO_1[i] indicates if the MPU MS_CTL.PC[3:0] protection context field can be set to the value 'i+1':
- PC_MASK_15_TO_1[i] is '0': MPU MS_CTL.PC[3:0] can NOT be set to 'i+1'; and PC[3:0] is not changed. If the protection context of the write transfer is '0', protection is not applied and PC[3:0] can be changed.
- PC_MASK_15_TO_1[i] is '1': MPU MS_CTL.PC[3:0] can be set to 'i+1'.
Note: When CPUSS_CM0_PC_CTL.VALID[i] is '1' (the associated protection context handler is valid), write transfers to PC_MASK_15_TO_1[i-1] always write '0', regardless of data written. This ensures that when valid protection context handlers are used to enter protection contexts 1, 2 or 3 through (HW modifies MPU MS_CTL.PC[3:0] on entry of the handler), it is NOT possible for SW to enter those protection contexts (SW modifies MPU MS_CTL.PC[3:0]).

SUBREGION_DISABLE
This field is used to individually disabled the eight equally sized subregions in which a region is partitioned. Subregion disable:
Bit 0: subregion 0 disable.
Bit 1: subregion 1 disable.
Bit 2: subregion 2 disable.
Bit 3: subregion 3 disable.
Bit 4: subregion 4 disable.
Bit 5: subregion 5 disable.
Bit 6: subregion 6 disable.

E.g., a 64 KByte address region (ATT0.REGION_SIZE is '15') has eight 8 KByte subregions. The access control as defined by ATT0 applies if the bus transfer address is within the address region AND the addressed subregion is NOT disabled. Note that the smallest region size is 256 B and the smallest subregion size is 32 B.

ADDR24
This field specifies the most significant bits of the 32-bit address of an address region. The region size is defined by ATT0.REGION_SIZE. A region of n Byte is always n Byte aligned.

REMAP
Specifies remapping of FLASH macro main region.
'0': No remapping.
'1': Remapping. The highest address bit of the FLASH main region is inverted. This effectively remaps the location of FLASH main region physical sectors in the logical address space. In other words, the higher half physical sectors are swapped with the lower half physical sectors.
Note: remapping only affects reading of the FLASH main region (over the R interface). It does NOT affect programming/erasing of the FLASH memory region (over the C interface).
E.g., for a 512 KB / 4 Mb main region, the logical address space ranges from [0x1000:0000, 0x1007:ffff] (the highest bit if the FLASH main region is bit 18). The memory has four physical sectors: sectors 0, 1, 2 and 3. If REMAP is '0', the physical regions logical addresses are as follows:
- The physical region 0: [0x1000:0000, 0x1001:ffff].
- The physical region 1: [0x1002:0000, 0x1003:ffff].
- The physical region 2: [0x1004:0000, 0x1005:ffff].
- The physical region 3: [0x1006:0000, 0x1007:ffff].
If REMAP is '1', the physical regions logical addresses are as follows:
- The physical region 0: [0x1004:0000, 0x1005:ffff].
- The physical region 1: [0x1006:0000, 0x1007:ffff].
- The physical region 2: [0x1000:0000, 0x1001:ffff].
- The physical region 3: [0x1002:0000, 0x1003:ffff].
Note: when the REMAP is changed, SW should invalidate the caches and buffers.

UP
Specifies direction in which Flash BIST steps through addresses:
''0': BIST steps through the Flash from the maximum row and column addresses (as specified by a design time configurtion parameter when ADDR_START_ENABLED is '0' and as specified by BIST_ADDR_START when ADDR_START_ENABLED is '1') to the minimum row and column addresses.
'1': BIST steps through the Flash from the minimum row and column addresses ('0' when ADDR_START_ENABLED is '0' and as specified by BIST_ADDR_START when ADDR_START_ENABLED is '1') to the maximum row and column addresses.
[2:2]
read-write
ROW_FIRST
Specifies how the Flash BIST addresses are generated:
'0': Column address is incremented/decremented till it reaches its maximum/minimum value. Once it reach its maximum/minimum value, it is set to its mimimum/maximum value and only then is the row address incremented/decremented.
'1': Row address is incremented/decremented till it reaches its maximum/minimum value. Once it reach its maximum/minimum value, it is set to its mimimum/maximum value and only then is the column address incremented/decremented.

ADDR_START_ENABLED
Specifies Flash BIST start addresses:
'0': Row and column addresses start with their maximum/minimum values.
'1': Row and column addresses start with their values as specified by BIST_ADDR_START.

Firmware sets this bit to enter HIBERNATE mode. The system will enter HIBERNATE mode immediately after writing to this bit and will wakeup only in response to XRES or WAKEUP event. Both UNLOCK and FREEZE must have been set correctly in a previous write operations. Otherwise, it will not enter HIBERNATE. External supplies must have been stable for 250us before entering HIBERNATE mode.

HVLVD1_EN
Enable HVLVD1 voltage monitor. When the LVD is enabled, it takes 20us for it to settle. There is no hardware stabilization counter, and it may falsely trigger during settling. It is recommended that firmware keep the interrupt masked for at least 8us, write a 1'b1 to the corresponding SRSS_INTR field to any falsely pended interrupt, and then optionally unmask the interrupt. After enabling, it further recommended to read the realted PWR_LVD_STATUS field, since the interrupt only triggers on edges. This bit is cleared (LVD is disabled) when entering DEEPSLEEP to prevent false interrupts during wakeup.

ACT_REG_BOOST
Controls the tradeoff between output current and internal operating current for the Active Regulator.

2'b00: 50uA
2'b01: 100uA
2'b10: 150uA
2'b11: 200uA

In all cases, the two related GPIO pins (WCO input and output pins) must be configured as analog connections using GPIO registers, and they must be hooked at the board level as described below. Configure this field before enabling the WCO, and do not change this setting when WCO_EN=1.

WRITE
Write bit
Only when this bit is set can the RTC registers be written to (otherwise writes are ignored). This bit cannot be set if the RTC is still busy with a previous update (see RTC_BUSY bit) or if the Read bit is set or getting set.
The user writes to the RTC user registers, when the Write bit is cleared by the user then the user registers content is copied to the actual RTC registers.
Only user RTC registers that were written to will get copied, others will not be affected.
When the SECONDS field is updated then TICKS will also be reset (WDT is not affected).
When the Write bit is cleared by a reset (brown out/DeepSleep) then the RTC update will be ignored/lost.
Do not set the Write bit if the RTC if the RTC is still busy with a previous update (see RTC_BUSY). Do not set the Write bit at the same time that the Read bit is cleared.

Calibration value for absolute frequency (at a fixed temperature). Each step causes 128 ticks to be added or removed each hour. Effectively that means that each step is 1.085ppm (= 128/(60*60*32,768)).
Positive values 0x01-0x3c (1..60) add pulses, negative values remove pulses, thus giving a range of +/-65.1 ppm (limited by 60 minutes per hour, not the range of this field)

All transactions for this channel uses the B field for the non-bufferable/bufferable access control ('hprot[2]').
[2:2]
read-write
PC
Protection context.
This field is set with the protection context of the transaction that writes this register; i.e. the 'write data' is ignored and instead the context is inherited from the write transaction (note the field attributes should be HW:RW, SW:R).
All transactions for this channel uses the PC field for the protection context.
[7:4]
read-write
PRIO
Channel priority:
'0': highest priority.
'1'
'2'
'3': lowest priority.
Channels with the same priority constitute a priority group. Priority decoding determines the highest priority pending channel. This channel is determined as follows. First, the highest priority group with pending channels is identified. Second, within this priority group, roundrobin arbitration is applied. Roundrobin arbitration (within a priority group) gives the highest priority to the lower channel indices (within the priority group).
[17:16]
read-write
PREEMPTABLE
Specifies if the channel is preemptable.
'0': Not preemptable.
'1': Preemptable. This field allows higher priority pending channels (from a higer priority group; i.e. an active channel can NOT be preempted by a pending channel in the same priority group) to preempt the active channel in between 'single transfers' (a 1D transfer consists out of X_COUNT single transfers; a 2D transfer consists out of X_COUNT*Y_COUNT single transfers). Preemption will NOT affect the pending status of channel. As a result, after completion of a higher priority activated channel, the current channel may be reactivated.
[18:18]
read-write
ENABLED
Channel enable:
'0': Disabled. The channel's trigger is ignored and the channel cannot be made pending and therefore cannot be made active. If a pensding channel is disabled, the channel is made non pending. If the activate channel is disabled, the channel is de-activated (bus transactions are completed).
'1': Enabled.
SW sets this field to '1' to enable a specific channel.
HW sets this field to '0' on an error interrupt cause (the specific error is specified by CH_STATUS.INTR_CAUSE).

START
FW sets this field to '1' to start a program operation. HW sets this field to '0' to indicate that the operation has completed.
Note: it is good practice to verify the result of a program operation by reading back a programmed eFUSE memory location. Programming can only change an eFUSE memory bit from '0' to '1'; i.e. a programming operation is a 'one-off' operation for each eFUSE memory bit: once a bit is changed to '1', it can NEVER be changed back to '0' as a hardware fuse is blown.
Programming a memory bit to '1' requires blowing a fuse and requires an eFUSE macro operation. Therefore, this programmiong operation takes time (as specified by the SEQ_PROGRAM_CTL reguisters). Programming amemory bit to '0' does not require an eFUSE macro operation (it is the default eFUSE macro state). Therefore, this programming operation is almost instantaneous.
Note: during a program operation, a read operation can not be performed. An AHB-Lite read transfer to the eFUSE memory during a program operation results in an AHB-Lite bus error.

'1': A duration is monitored. No edge detection is done. The monitored signal is taken as a (high active) level signal for enabling the profiling counter.
Note: All monitor signals which only can represent events are edge encoded in hardware, therefore a selection of CTL.CNT_DURATION=1 will not produce meaningful results.

DRIVE_MODE0
The GPIO drive mode for IO pin 0. Resistive pull-up and pull-down is selected in the drive mode.
Note: when initializing IO's that are connected to a live bus (such as I2C), make sure the peripheral and HSIOM (HSIOM_PRT_SELx) is properly configured before turning the IO on here to avoid producing glitches on the bus.
Note: that peripherals other than GPIO & UDB/DSI directly control both the output and output-enable of the output buffer (peripherals can drive strong 0 or strong 1 in any mode except OFF='0').
Note: D_OUT, D_OUT_EN are pins of GPIO cell.

VDDIO_ACTIVE
Indicates presence or absence of VDDIO supplies (i.e. other than VDDD, VDDA) on the device (supplies are numbered 0..n-1). Note that VDDIO supplies have basic (crude) supply detectors only. If separate, robust, brown-out detection is desired on IO supplies, on-chip or off-chip analog resources need to provide it. For these bits to work reliable, the supply must be within valid spec range (per datasheet) or held at ground. Any in-between voltage has an undefined result.
'0': Supply is not present
'1': Supply is present
When multiple VDDIO supplies are present, they will be assigned in alphanumeric ascending order to these bits during implementation.
For example 'vddusb, vddio_0, vddio_a, vbackup, vddio_r, vddio_1' are present then they will be assigned to these bits as below:
0: vbackup,
1: vddio_0,

Bypass of the programmable IO, one bit for each IO pin: BYPASS[i] is for IO pin i. When ENABLED is '1', this field is used. When ENABLED is '0', this field is NOT used and SMARTIO fabric is always bypassed.

'15': chip_data[7]/'1'.
'16': clk_smartio/rst_sys_act_n. Used for both Active functionality synchronous logic on 'clk_smartio'. This selection is intended for synchronous operation on a PCLK specified clock frequency ('clock_smartio_pos_en'). Note that the fabric's clocked elements are frequency aligned, but NOT phase aligned to 'clk_sys'.
'17': clk_smartio/rst_sys_dpslp_n. Used for both DeepSleep functionality synchronous logic on 'clk_smartio' (note that 'clk_smartio' is NOT available in DeepSleep and Hibernate power modes). This selection is intended for synchronous operation on a PCLK specified clock frequency ('clock_smartio_pos_en'). Note that the fabric's clocked elements are frequency aligned, but NOT phase aligned to 'clk_sys'.
'18': Same as '17'. Note that the M0S8 SMARTIO version used the Hibernate reset for this value, but the MXS40 SMARTIO version does not support Hibernate functionality.
'19': clk_lf/rst_lf_dpslp_n (note that 'clk_lf' is available in DeepSleep power mode). This selection is intended for synchronous operation on'clk_lf'. Note that the fabric's clocked elements are frequency aligned, but NOT phase aligned to other 'clk_lf' clocked elements.
'20'-'30': Clock source is constant '0'. Any of these clock sources should be selected when the IP is disabled to ensure low power consumption.
'31': asynchronous mode/'1'. Select this when clockless operation is configured.
NOTE: Two positive edges of the selected clock are required for the block to be enabled (to deactivate reset). In asynchronous (clockless) mode clk_sys is used to enable the block, but is not available for clocking.

HLD_OVR
IO cell hold override functionality. In DeepSleep power mode, the HSIOM holds the IO cell output and output enable signals if Active functionality is connected to the IO pads. This is undesirable if the SMARTIO is supposed to deliver DeepSleep output functionality on these IO pads. This field is used to control the hold override functionality from the SMARTIO:
'0': The HSIOM controls the IO cell hold override functionality ('hsiom_hld_ovr').
'1': The SMARTIO controls the IO cel hold override functionality:
- In bypass mode (ENABLED is '0' or BYPASS[i] is '1'), the HSIOM control is used.
- In NON bypass mode (ENABLED is '1' and BYPASS[i] is '0'), the SMARTIO sets hold override to 'pwr_hld_ovr_hib' to enable SMARTIO functionality in DeepSleep power mode (but disables it in Hibernate or Stop power mode).

ENABLED
Enable for programmable IO. Should only be set to '1' when the programmable IO is completely configured:
'0': Disabled (signals are bypassed; behavior as if BYPASS is 0xFF). When disabled, the fabric (data unit and LUTs) reset is activated.
If the IP is disabled:
- The PIPELINE_EN register field should be set to '1', to ensure low power consumption by preventing combinatorial loops.
- The CLOCK_SRC register field should be set to '20'-'30' (clock is constant '0'), to ensure low power consumption.
'1': Enabled. Once enabled, it takes 3 'clk_fabric' clock cycles till the fabric reset is de-activated and the fabric becomes fully functional. This ensures that the IO pins' input synchronizer states are flushed when the fabric is fully functional.

SENSE_DIV
The length-1 of the Sense modulation 'clock' period in clk_csd cycles. For regular CSD one sense clock cycle = one conversion (=phi1+phi2) .
Note this is the base divider, clock dithering may change the actual period length.
Note that SENSE_DIV must be at least 1 and additionally also allow for one clk_hf of non overlap (if OVERLAP_HI1/2 is set) on both phases, i.e. if clk_csd=clk_hf then SENSE_DIV must be >=3.
In addition the FILTER_DELAY needs to be added to the minimum allowed SENSE_DIV value.
[11:0]
read-write
LFSR_SIZE
Selects the length of the LFSR which determines the LFSR repeat period. LFSR_BITS LSB of the LFSR are used for the clock dithering variation on the base period (was PRS in CSDv1). Whenever the LFSR is used (non zero value in this field) the LFSR_CLEAR bit should also be set.

LFSR_SCALE
Shift the LFSR output left by LSFR_SCALE bits before adding to SENSE_DIV. This dithering is disabled when SEL_LSFR_MSB is set.
The clock divider to be used = (SENSE_DIV+1) + (SEL_LSFR_MSB ? 0 : (LFSR_OUT<<LFSR_SCALE)).
Note that the clock divider including the dithering term must fit in 12 bits, otherwise the result is undefined.
[23:20]
read-write
LFSR_CLEAR
When set, forces the LFSR to it's initial state (all ones). This bit is automatically cleared by hardware after the LFSR is cleared, which is at the next clk_csd positive edge. This bit should be set whenever this register is written and the LFSR is used.
Note that the LFSR will also get reset to all ones during the AutoZero_1/2 states.
[24:24]
read-write
SEL_LFSR_MSB
Use the MSB of configured LSFR size as csd_sense signal. Intended to be used only with bit 8 or 12-bit LFSR size for CSDv1 backward compatibility (PRS). When this bit is set then clock divider dithering is disabled and SENSE_WIDTH is disabled.
[25:25]
read-write
LFSR_BITS
Selects the number of LSB bits to use from the LSFR to provide the clock dithering variation on the base period.
Caveat make sure that SENSE_DIV > the maximum absolute range (e.g. for 4B SENSE_DIV > 8), otherwise results are undefined.

SENSE_WIDTH
Defines the length of the first phase of the sense clock in clk_csd cycles.
A value of 0 disables this feature and the duty cycle of csd_sense will be 50 percent, which is equal to SENSE_WIDTH = (SENSE_DIV+1)/2, or when clock dithering is used that becomes [(SENSE_DIV+1) + (LFSR_OUT << LSFR_SCALE)]/2. At all times it must be assured that the phases are at least 2 clk_csd cycles (1 for non overlap, if used), if this rule is violated the result is undefined.
Note that this feature is not available when SEL_LFSR_MSB (PRS) is selected.

OVERLAP_PHI1
NonOverlap or not for Phi1 (csd_sense=0).
0 = Non-overlap for Phi1, the Phi1 signal is csd_sense inverted except that the signal goes low 1 clk_sample before csd_sense goes high. Intended usage: new low EMI CSD/CSX with static GPIO.
1 = 'Overlap' (= not non-overlap) for Phi1, the Phi1 signal is csd_sense inverted. Intended usage: legacy CSD with GPIO switching, the GPIO internal circuit ensures that the switches are non-overlapping.

COUNTER_ENABLED
Counter enables for counters 0 up to CNT_NR-1.
'0': counter disabled.
'1': counter enabled.
Counter static configuration information (e.g. CTRL.MODE, all TR_CTRL0, TR_CTRL1, and TR_CTRL2 register fields) should only be modified when the counter is disabled. When a counter is disabled, command and status information associated to the counter is cleared by HW, this includes:
- the associated counter triggers in the CMD register are set to '0'.
- the counter's interrupt cause fields in counter's INTR register.
- the counter's status fields in counter's STATUS register..
- the counter's trigger outputs ('tr_overflow', 'tr_underflow' and 'tr_compare_match').
- the counter's line outputs ('line_out' and 'line_compl_out').
In multi-core environments, use the CTRL_SET/CTRL_CLR registers to avoid race-conditions on read-modify-write attempts to this register.

PWM_SYNC_KILL
Specifies asynchronous/synchronous kill behavior:
'1': synchronous kill mode: the kill event disables the 'dt_line_out' and 'dt_line_compl_out' signals till the next terminal count event (synchronous kill). In synchronous kill mode, STOP_EDGE should be RISING_EDGE.
'0': asynchronous kill mode: the kill event only disables the 'dt_line_out' and 'dt_line_compl_out' signals when present. In asynchronous kill mode, STOP_EDGE should be NO_EDGE_DET.
This field has a function in PWM and PWM_DT modes only. This field is only used when PWM_STOP_ON_KILL is '0'.

QUADRATURE_MODE
In QUAD mode selects quadrature encoding mode (X1/X2/X4).
In PWM, PWM_DT and PWM_PR modes, these two bits can be used to invert 'dt_line_out' and 'dt_line_compl_out'. Inversion is the last step in generation of 'dt_line_out' and 'dt_line_compl_out'; i.e. a disabled output line 'dt_line_out' has the value QUADRATURE_MODE[0] and a disabled output line 'dt_line_compl_out' has the value QUADRATURE_MODE[1].

CC_MATCH_MODE
Determines the effect of a compare match event (COUNTER equals CC register) on the 'line_out' output signals. Note that INVERT is especially useful for center aligned pulse width modulation.
To generate a duty cycle of 0 percent, the counter CC register should be set to '0'. For a 100 percent duty cycle, the counter CC register should be set to larger than the counter PERIOD register.

LS_EN_STAT
LS enable status bit. This bit is a copy of LS_EN that is synchronized to the low speed clock domain and back to the system clock domain. Firmware can use this bit to observe whether LS_EN has taken effect in the low speed clock domain. Firmware should never change the configuration for the LS generator without ensuring this bit is 0.
The following procedure should be followed to disable the LS generator:
1. If LS_EN=0 we are done. Exit the procedure.
2. Check that LS_EN_STAT=1. If not, wait until it is. This will catch the case of a recent enable (LS_EN=1) that has not taken effect yet.
3. Set LS_EN=0.
4. Wait until LS_EN_STAT=0.

The peer address registers are used for multiple purposes. The register is written by firmware to provide the peer address to be used for a hardware procedure. When firmware reads the register, it reads back peer address values updated by hardware.
While doing directed Advertising, the firmware writes the peer address of the device specified by the Di-rect_Address parameter of the LE_Set_Advertising_Parameters command.
In non MMMS mode, While device is configured as an initiator without white list filtering, the peer address specified in the peer_address field of the create connection command is programmed into this register, which is used by hard-ware procedures.
In non MMMS mode, While device is configured as an initiator and white list is enabled, firmware can read this register to get the address of the peer device from which connectable ADV packet was received and to which the connection is created.
When a connection is created as a slave, the firmware can read this register to get the address of the peer de-vice to which connection is created.

OSC_STARTUP_DELAY
Oscillator stabilization/startup delay. This is in X.Y for-mat where X is in terms of number of BT slots (625 us) and Y is in terms of number of clock periods of 16KHz clock input, required for RF oscillator to stabilize the clock output to the controller on its output pin, after oscillator is turned ON. In this period the clock is as-sumed to be unstable, and so the controller does not turn on the clock to internal logic till this period is over. This means, the wake up from deep sleep mode must account for this delay before the wakeup instant.
Osc_startup_delay[7:5] is number of slots(625us)
Osc_startup_delay[4:0 is number of clock periods of 16KHz clock

CONNECTION_EVENT_LENGTH
This field defines the length of Connection event. This value is derived from the CE length HCI parameters received from the host. This determines the number of master transmit slots in a connection event, subject to either of the MD bits being set. If both MD bits are set to 0, this has no effect. Units: 625us
Note:
The connection event length as specified by the CE_LENGTH shall not exceed CONN_INTERVAL - 1.25 ms.
The CE-length parameter, according to the Bluetooth specification, is the length of the connection event.
Take an example to illustrate this scenario:
Assume a connection with interval = 100ms. that the application has put allowed 20ms of CE-length.
Here, the CE-length can be upto 100ms (100ms - 150us to be exact).
If the connection is maintained for 5 minutes, there could be 10*60*5 = 3000 connection-intervals.
The CE-length need not be maintained constant during all the 3000 connection events.
Here are the typical cases that determine the value of CE-length:
(1) No data packets exchanged. we are just maintaining time and frequency synchronization. In this case, only a packet pair will be exchanged every connection interval. Here, CE-length = 1.
(2) Average of 10 packets to be sent per connection event.
We can pump data in multiple ways here:
2.1: Send data at uniform rate : In this case, the CE-length will be enough to accommodate 10 packets, which will take about 7ms. As this is less than application enforced limit of 20ms, we can comfortably push all the 10 data packets in this connection interval. So data will be pumped to the other BT device at the same rate as is received from my application.
2.2: Can send data in bursts. Assume that we accumulate data for 1 second and pump out at the end of 1 second(this is not done by our Bluetooth stack, the application needs to buffer the data). So, at 10th connection interval, we have 100 packets accumulated. We are now ready to pump this data. 100 packets take about 70 ms. This is above the application enforced 20ms. So, the hardware can pump data that can fill up 20ms. The remaining data will be deferred to the next connection interval.
So, in this case, you would see a CE-length spread over time like this (Per connection interval):
0,0,0,0,0,0,0,0,0,0, 20,20,20,10,0,0,0,0,0,0, 20,20,20,10,0,0,0,0,0,0, 20,20,20,10,0,0,0,0,0,0,
and so on.
(3) We are receiving data at the same rate as in (2). This case is to honor data sent by the other BT-device by giving it more time in the current connection interval.
In (2) and (3) you will see non-empty packets either transmitted or received. We can also utilize the CE-length for different reasons:
(4) A transaction is in progress, and we are expecting a response packet very soon. In this case, we may be exchanging only empty packets now, and in the next few packet-pairs.
In this case, you will the CE-length to be large, and a non-empty packet may not be exchanged in all the slots.

Read: Reads TX_SENT[3:0].
The bits in this field indicate the status of the SENT bit in the hard-ware for each packet buffer. The bit values are
1 - queued
0 - no packet / packet ack received by hardware
Example1: If the read value is : 0x03, then packets in buffer 0 and buffer 1 are in the queue to be transmitted. All the other FIFOs are empty or hardware has cleared them after receiving acknowledgement.
NOTE:
The SENT status bit and ACK status bit have to be taken together to understand the meaning of packet status. The table below describes how the two bits are sequentially updated by either hardware/firmware to complete one data transmission.
SENT ACK Description
0 0 Buffer is empty. No packet is queued in the buffer
1 0 Packet is queued by firmware.
1 1 Packet is transmitted by hardware. Hardware is waiting for acknowledgement.
0 1 Hardware has received ACK. Firmware has not yet processed the ACK.

SET_CLEAR
Write: Used to set the SENT bit in hardware for the selected packet buffer.
1 - packet queued
When firmware has a packet to send, firmware first loads the next available packet buffer. Then the hardware SENT bit is set by writing 1 to this bit field along with the list_index field that identified the buffer index. This indicates that a packet has been queued in the data buffer for sending. This packet is now ready to be transmitted.
The SENT bit in hardware is cleared by hardware only when it has received an acknowledgement from the remote device.
Firmware typically does not clear the bit. However, It only clears the bit on its own if it needs to 'flush' a packet from the buffer, without waiting to receive acknowledgement from the remote device, firmware clears BIT7 along with the list_index specified.

Read: Reads TX_ACK[3:0]
If a particular bit is set, then the packet in the selected buffer has been transmitted (at least once) by the hardware and hardware is waiting for acknowledgement.
Example1 : If the read value is : 0x03, then packets in FIFO-0 and FIFO-1 are acknowledged by the remote device. These acknowledgements are pending to be processed by firmware.
Example2 : If the read value is : 0x02, then packet FIFO-1 is acknowledged by the remote device. This acknowledgement is pending to be processed by firmware.

SET_CLEAR
Write: Firmware uses the field to clear and ACK bit in the hardware to indicate that the acknowledgement for the transmit packet has been received and processed by firmware.
Firmware clears the ACK bit in the hardware by writing in this register only after the acknowledgement is processed successfully by firmware.
For clearing ack for a packet transmitted in fifo-index : '3', firm-ware will write '3' in the 'list-index' field and set this bit (BIT7) to 0.
This is the indication that the corresponding packet buffer identi-fied by List-Index is cleared of previous transmission and can be re-used for another packet from now on.
The ACK bit in hardware is set by hardware when it has success-fully transmitted a packet.

PDU_RESP_TIME_VAL
Non MMMS mode: This register is loaded with the count value to monitor the time to get a response for a PDU from peer device.
Firmware starts the timer by issuing the command, RESP_TIMER_ON, after it has queued a PDU for transmission, that requires a response.
If a response is received, firmware stops and clears the timer by issuing the command RESP_TIMER_OFF.
If this timer expires, it results in hardware closing the connection and triggering a conn_closed interrupt.
The discon_status field in the Connection status register is set with the appropriate reason.
Units : Milliseconds.
Resolution : 1.25 ms
MMMS mode: This register is loaded with a count value, which when matched by the internal timer, triggers the GEN_TIMER_INTR. This is recommended to be used as a one shot timer and not as a periodic timer.
Firmware starts the timer by loading the expiry time and issuing the command, RESP_TIMER_ON.
Once the timer expiry is triggered with the interrupt GEN_TIMER_INTR, the firmware stops the timer by issuing the command RESP_TIMER_OFF.

SET_CLEAR_C1
Write: Used to set the SENT bit in hardware for the selected packet buffer.
1 - packet queued
When firmware has a packet to send, firmware first loads the next available packet buffer.

This indicates that a packet has been queued in the data buffer for sending. This packet is now ready to be transmitted.
The SENT bit in hardware is cleared by hardware only when it has received an acknowledgement from the remote device.
Firmware typically does not clear the bit. However, It only clears the bit on its own if it needs to 'flush' a packet from the buffer, without waiting to receive acknowledgement from the remote device, firmware clears BIT7 along with the list_index specified.

SET_CLEAR_C1
Write: Firmware uses the field to clear and ACK bit in the hardware to indicate that the acknowledgement for the transmit packet has been received and processed by firmware.
Firmware clears the ACK bit in the hardware by writing in this register only after the acknowledgement is processed successfully by firmware.
For clearing ack for a packet transmitted in fifo-index : '3', firm-ware will write '3' in the 'list-index' field and set this bit (BIT7) to 0.
This is the indication that the corresponding packet buffer identi-fied by List-Index is cleared of previous transmission and can be re-used for another packet from now on.
The ACK bit in hardware is set by hardware when it has success-fully transmitted a packet.

The default number of buffers in the IP is 5. The index range is 0-3.
Read: Reads TX_SENT[3:0].
The bits in this field indicate the status of the SENT bit in the hard-ware for each packet buffer. The bit values are
1 - queued
0 - no packet / packet ack received by hardware
Example1: If the read value is : 0x03, then packets in buffer 0 and buffer 1 are in the queue to be transmitted. All the other FIFOs are empty or hardware has cleared them after receiving acknowledgement.
[3:0]
read-write
SET_CLEAR_C1
Write: Used to set the SENT bit in hardware for the selected packet buffer.
1 - packet queued
When firmware has a packet to send, firmware first loads the next available packet buffer. Then the hardware SENT bit is set by writing 1 to this bit field along with the list_index field that identified the buffer index. This indicates that a packet has been queued in the data buffer for sending. This packet is now ready to be transmitted.
The SENT bit in hardware is cleared by hardware only when it has received an acknowledgement from the remote device.
Firmware typically does not clear the bit. However, It only clears the bit on its own if it needs to 'flush' a packet from the buffer, without waiting to receive acknowledgement from the remote device, firmware clears BIT7 along with the list_index specified.

- When issuing a token again after the token interrupt flag (CMPIRQ) has been set to '1', wait for 3 cycles or more after a USB transfer clock (12 MHz in the full-speed mode, 1.5 MHz in the low-speed mode) was output, then write data to this bit.
- Read the value of TKNEN bit if a new value is written in it .Continue writing in this bit until a retrieved value equals a new value written in. During this checking process, it is needed to prevent any interrupt.
- Take the following steps when CMPIRQ bit of Interrupt USB Host Register (INTR_USBHOST) is set to '1' by finishing IN token or Isochronous IN token.
1. Read HS bit of Host Error Status Register (HOST_ERR), then set CMPIRQ bit to '0'.
2. Set EPn bit of Host DMA Enable Register (HOST_DMA_ENBL) (n=1 or 2) to '1' if HS bit of Host Error Status Register (HOST_ERR) is equal to '00' and wait until EPn bit of Host DMA Data Request Register (HOST_DMA_DREQ) changes to '1'. Finish the IN token processing if HS bit is not equal to '00'.

[0:0]
read-write
MMIO_MODE
'0': MMIO mode. Individual MMIO accesses to TX and RX FIFOs are used to generate a sequence of SPI transfers. This mode of operation allows for large flexibility in terms of the SPI transfers that can be generated.
0
XIP_MODE
1': XIP mode. eXecute-In-Place mode: incoming read and write transfers over the AHB-Lite bus infrastructure are automatically translated in SPI transfers to read data from and write data to a device. This mode of operation allow for efficient device read and write operations. This mode is only supported in SPI_MODE.
1
CLOCK_IF_RX_SEL
Specifies device interface receiver clock 'clk_if_rx' source. MISO data is captured on the rising edge of 'clk_if_rx'.
'0': 'spi_clk_out' (internal clock)
'1': !'spi_clk_out' (internal clock)
'2': 'spi_clk_in' (feedback clock)
'3': !'spi_clk_in' (feedback clock)
Note: the device interface transmitter clock 'clk_if_tx' is fixed and is 'spi_clk_out' MOSI data is driven on the falling edge of 'clk_if_tx'.
[13:12]

DESELECT_DELAY
Specifies the minimum duration of SPI deselection ('spi_select_out[]' is high/'1') in between SPI transfers:
'0': 1 interface clock cycle.
'1': 2 interface clock cycles.
'2': 3 interface clock cycles.
'3': 4 interface clock cycles.
'4': 5 interface clock cycles.
'5': 6 interface clock cycles.
'6': 7 interface clock cycles.
'7': 8 interface clock cycles.
During SPI deselection, 'spi_select_out[]' are '1'/inactive, 'spi_data_out[]' are '1' and 'spi_clk_out' is '0'/inactive.

BLOCK
Specifies what happens for MMIO interface read accesses to an empty RX data FIFO or to a full TX format/data FIFO. Note: the FIFOs can only be accessed in MMIO_MODE.
This field is not used for test controller accesses.
[24:24]
read-write
BUS_ERROR
0': Generate an AHB-Lite bus error. This option is useful when SW decides to use polling on STATUS.TR_BUSY to determine if a interface transfer is no longer busy (transfer is completed). This option adds SW complexity, but limits the number of AHB-Lite wait states (and limits ISR latency).
0
WAIT_STATES
1': Introduce wait states. This setting potentially locks up the AHB-Lite infrastructure and may increase the CPU interrupt latency.This option is useful when SW performs TX/RX data FIFO accesses immediately after a command is setup using the TX format FIFO. This option has low SW complexity, but may result in a significant number of AHB-Lite wait states (and may increase ISR latency).
1
ENABLED
IP enable:
'0': Disabled. All non-retention registers are reset to their default value when the IP is disabled. When the IP is disabled, the XIP accesses produce AHB-Lite bus errors.
'1': Enabled.
Note: Before disabling the IP, SW should ensure that the IP is NOT busy (STATUS.BUSY is '0'), otherwise illegal interface transfers may occur.

When BUSY is '0', the IP can be safely disabled without:
- the potential loss of transient write data.
- the potential risk of aborting an inflight SPI device interface transfer.
When BUSY is '0', the mode of operation (XIP_MODE or MMIO_MODE) can be safely changed.

DATA20
Command data. The higher two bits DATA[19:18] specify the specific command
'0'/TX: A SPI transfer always start with a TX command FIFO entry of the 'TX' format.
- DATA[17:16] specifies the width of the data transfer:
- '0': 1 bit/cycle (single data transfer).
- '1': 2 bits/cycle (dual data transfer).
- '2': 4 bits/cycle (quad data transfer).
- '3': 8 bits/cycle (octal data transfer).
- DATA[15]: specifies whether this is the last TX Byte; i.e. whether the 'spi_select_out[3:0]' IO output signals are de-activated after the transfer.
- DATA[11:8] specifies which of the four devices are selected. DATA[11:8] are directly mapped to 'spi_select_out[3:0]'. Two devices can be selected at the same time in dual-quad mode.
- '0': device deselected
- '1': device selected
- DATA[7:0] specifies the transmitted Byte.
'1'/TX_COUNT: The 'TX_COUNT' command relies on the TX data FIFO to provide the transmitted bytes. The 'TX_COUNT' command is ALWAYS considered to be the last command of a SPI data transfers.
- DATA[17:16] specifies the width of the transfer.
- DATA[15:0] specifies the number of to be transmitted Bytes (minus 1) from the TX data FIFO.
'2'/RX_COUNT: The 'RX_COUNT' command relies on the RX data FIFO to accept the received bytes. The 'RX_COUNT' command is ALWAYS considered to be the last command of a SPI data transfers.
- DATA[17:16] specifies the width of the transfer.
- DATA[15:0] specifies the number of to be transmitted Bytes (minus 1) to the RX data FIFO.
'3'/DUMMY_COUNT: The 'DUMMY_COUNT' command conveys dummy cycles. Dummy cycles are used to implement a Turn-Around time in which the SPI master changes from a transmitter driving the data lines to a receiver receiving on the same data lines. The 'DUMMY_COUNT' command is ALWAYS considered to be NOT the last command of a SPI data transfers; i.e. it needs to be followed by another command.
- DATA[15:0] specifies the number of dummy cycles (minus 1). In dummy cycles, the data lines are not driven.

START
SW sets this field to '1' to start a AES-128 forward block cipher operation (on the address in CRYPTO_ADDR). HW sets this field to '0' to indicate that the operation has completed. Once completed, the result of the operation can be read from CRYPTO_RESULT0, ..., CRYPTO_RESULT3.
The operation takes roughly 13 clk_hf clock cycles.
Note: An operation can only be started in MMIO_MODE.

Specifies the base address of the device region. If the device region is 2^m Bytes, ADDR MUST be a multiple of 2^m.
In dual quad SPI data transfer, the two devices should have the same ADDR and MASK register settings. The device control information (ADDR_CTL, RD_CMD_CTL, etc.) are provided by the MMIO control registers of the device with the lowest index.
The most significant bit fields are constants and set based on the SMIF_XIP_ADDR parameter. The most significant bits are identified on the SMIF_XIP_MASK parameter. E.g., if SMIF_XIP_MASK is 0xff00:0000 (16 MB XIP memory region), ADDR[31:24] = SMIF_XIP_ADDR[31:24].

The most significant bit fields are constants and set to'1'. The most significant bits are identified on the SMIF_XIP_MASK parameter. E.g., if SMIF_XIP_MASK is 0xff00:0000 (16 MB XIP memory region), MASK[31:24] = 0xff.

The lower significant address Bytes of the transfer request are used as XIP address to the external device. Note that for dual quad SPI data transfer, the transfer request address is divided by 2. Therefore, the transfer request address needs to be a multiple of 2. If the trasnfer requestaddress is NOT a multiple of 2, the XIP_ALIGNMENT_ERROR interrupt cause is activated.

This functionality is used for read and write operation in XIP, dual quad SPI mode; i.e. this DIV2 must be set to '1' in dual quad SPI mode. If the transfer request address is NOT a multiple of 2 or the requested number of Bytes is not a multiple of 2, the XIP_ALIGNMENT_ERROR interrupt cause is activated.

EC_AM_MODE
This field specifies the clocking for the address matching (I2C) or slave selection detection logic (SPI)
'0': Internally clocked mode
'1': Externally clocked mode
In internally clocked mode, the serial interface protocols run off the SCB clock. In externally clocked mode, the serial interface protocols run off the clock as provided by the serial interface.
The clocking for the rest of the logic is determined by CTRL.EC_OP_MODE.
Externally clocked mode is only used for synchronous serial interface protocols (SPI and I2C) in slave mode. In SPI mode, only Motorola submode (all Motorola modes: 0, 1, 2, 3) is supported.
In UART mode this field should be '0'.
[8:8]
read-write
EC_OP_MODE
This field specifies the clocking for the SCB block
'0': Internally clocked mode
'1': externally clocked mode
In internally clocked mode, the serial interface protocols run off the SCB clock. In externally clocked mode, the serial interface protocols run off the clock as provided by the serial interface.
Externally clocked operation mode is only used for synchronous serial interface protocols (SPI and I2C) in slave mode AND EZ mode. In SPI mode, only Motorola submode (all Motorola modes: 0, 1, 2, 3) is supported. The maximum SPI slave, EZ mode bitrate is 48 Mbps (transmission and IO delays outside the IP will degrade the effective bitrate).
In UART mode this field should be '0'.
[9:9]
read-write
EZ_MODE
Non EZ mode ('0') or EZ mode ('1').
In EZ mode, a meta protocol is applied to the serial interface protocol. This meta protocol adds meaning to the data frames transferred by the serial interface protocol: a data frame can represent a memory address, a write memory data element or a read memory data element. EZ mode is only used for synchronous serial interface protocols: SPI and I2C. In SPI mode, only Motorola submode (all Motorola modes: 0, 1, 2, 3) is supported and the transmitter should use continuous data frames; i.e. data frames not seperated by slave deselection. This mode is only applicable to slave functionality. In EZ mode, the slave can read from and write to an addressable memory structure of 32 bytes. In EZ mode, data frames should 8-bit in size and should be transmitted and received with the Most Significant Bit (MSB) first.
In UART mode this field should be '0'.

ADDR_ACCEPT
Determines whether a received matching address is accepted in the RX FIFO ('1') or not ('0').
In I2C mode, this field is used to allow the slave to put the received slave address or general call address in the RX FIFO. Note that a received matching address is put in the RX FIFO when this bit is '1' for both I2C read and write transfers.
In multi-processor UART receiver mode, this field is used to allow the receiver to put the received address in the RX FIFO. Note: non-matching addresses are never put in the RX FIFO.
[16:16]
read-write
BLOCK
Only used in externally clocked mode. If the externally clocked logic and the internal CPU accesses to EZ memory coincide/collide, this bit determines whether the CPU access should block and result in bus wait states ('BLOCK is 1') or not (BLOCK is '0'). IF BLOCK is '0' and the accesses collide, CPU read operations return 0xffff:ffff and CPU write operations are ignored. Colliding accesses are registered as interrupt causes: INTR_TX.BLOCKED and INTR_RX.BLOCKED.

ENABLED
SCB block is enabled ('1') or not ('0'). The proper order in which to initialize SCB is as follows:
- Program protocol specific information using SPI_CTRL, UART_CTRL (and UART_TX_CTRL and UART_RX_CTRL) or I2C_CTRL registers. This includes selection of a submode, master/slave functionality and transmitter/receiver functionality when applicable.
- Program generic transmitter (TX_CTRL) and receiver (RX_CTRL) information. This includes enabling of the transmitter and receiver functionality.
- Program transmitter FIFO (TX_FIFO_CTRL) and receiver FIFO (RX_FIFO_CTRL) information.
- Program CTRL register to enable SCB, select the specific operation mode and oversampling factor.
When this block is enabled, no control information should be changed. Changes should be made AFTER disabling this block, e.g. to modify the operation mode (from I2C to SPI) or to go from externally to internally clocked. The change takes effect after the block is re-enabled. Note that disabling the block will cause re-initialization of the design and associated state is lost (e.g. FIFO content).

Note that the INTR_TX.BLOCKED and INTR_RX.BLOCKED interrupt causes are used to indicate whether a SW access was actually blocked by externally clocked logic.

SSEL_CONTINUOUS
Continuous SPI data transfers enabled ('1') or not ('0'). This field is used in master mode. In slave mode, both continuous and non-continuous SPI data transfers are supported independent of this field.
When continuous transfers are enabled individual data frame transfers are not necessarily seperated by slave deselection (as indicated by the level or pulse on the SELECT line): if the TX FIFO has multiple data frames, data frames are send out without slave deselection.
When continuous transfers are not enabled individual data frame transfers are always seperated by slave deselection: independent of the availability of TX FIFO data frames, data frames are sent out with slave deselection.

LIN_MODE
Only applicable in standard UART submode. When '1', the receiver performs break detection and baud rate detection on the incoming data. First, break detection counts the amount of bit periods that have a line value of '0'. BREAK_WIDTH specifies the minum required amount of bit periods. Successful break detection sets the INTR_RX.BREAK_DETECT interrupt cause to '1'. Second, baud rate detection counts the amount of peripheral clock periods that are use to receive the synchronization byte (0x55; least significant bit first). The count is available through UART_RX_STATUS.BR_COUNTER. Successful baud rate detection sets the INTR_RX.BAUD_DETECT interrupt cause to '1' (BR_COUNTER is reliable). This functionality is used to synchronize/refine the receiver clock to the transmitter clock. The receiver software can use the BR_COUNTER value to set the right IP clock (from the programmable clock IP) to guarantee successful receipt of the first LIN data frame (Protected Identifier Field) after the synchronization byte.

This field is used during an address match or general call address in internally clocked mode
Only used when:
- EC_AM_MODE is '0', EC_OP_MODE is '0', S_GENERAL_IGNORE is '0] and non EZ mode.
Functionality is as follows:
- 1: a received (matching) slave address is immediately NACK'd when the receiver FIFO is full.
- 0: clock stretching is performed (till the receiver FIFO is no longer full).
For externally clocked logic (EC_AM is '1') on an address match or general call address (and S_GENERAL_IGNORE is '0'). Only used when (NOT used when EC_AM is '1' and EC_OP is '1' and address match and EZ mode):
- EC_AM is '1' and EC_OP is '0'.
- EC_AM is '1' and general call address match.
- EC_AM is '1' and non EZ mode.
Functionality is as follows:
- 1: a received (matching or general) slave address is always immediately NACK'd. There are two possibilities:
1). the SCB clock is available (in Active system power mode) and it handles the rest of the current transfer. In this case the I2C master will not observe the NACK.
2).SCB clock is not present (in DeepSleep system power mode). In this case the I2C master will observe the NACK and may retry the transfer in the future (which gives the internally clocked logic the time to wake up from DeepSleep system power mode).
- 0: clock stretching is performed (till the SCB clock is available). The logic will handle the ongoing transfer as soon as the clock is enabled.

BUS_BUSY
I2C bus is busy. The bus is considered busy ('1'), from the time a START is detected or from the time the SCL line is '0'. The bus is considered idle ('0'), from the time a STOP is detected. If SCB block is disabled, BUS_BUSY is '0'. After enabling the block, it takes time for the BUS_BUSY to detect a busy bus. This time is the maximum high time of the SCL line. For a 100 kHz interface frequency, this maximum high time may last roughly 5 us (half a bit period).
For single master systems, BUS_BUSY does not have to be used to detect an idle bus before a master starts a transfer using I2C_M_CMD.M_START (no bus collisions).
For multi-master systems, BUS_BUSY can be used to detect an idle bus before a master starts a transfer using I2C_M_CMD.M_START_ON_IDLE (to prevent bus collisions).

M_START
When '1', transmit a START or REPEATED START. Whether a START or REPEATED START is transmitted depends on the state of the master state machine. A START is only transmitted when the master state machine is in the default state. A REPEATED START is transmitted when the master state machine is not in the default state, but is working on an ongoing transaction. The REPEATED START can only be transmitted after a NACK or ACK has been received for a transmitted data element or after a NACK has been transmitted for a received data element. When this action is performed, the hardware sets this field to '0'.

M_START_ON_IDLE
When '1', transmit a START as soon as the bus is idle (I2C_STATUS.BUS_BUSY is '0', note that BUSY has a default value of '0'). For bus idle detection the hardware relies on STOP detection. As a result, bus idle detection is only functional after at least one I2C bus transfer has been detected on the bus (default/reset value of BUSY is '0') . A START is only transmitted when the master state machine is in the default state. When this action is performed, the hardware sets this field to '0'.

Each IO cell 'xxx' has two associated IP output signals 'xxx_out_en' and 'xxx_out'.

In this operation mode, for an IO cell 'xxx' that is used as an output, the 'xxx_out_en' output enable signal is typically constant '1' the 'xxx_out' output is the outputted value. In other words, in normal operation mode, the 'xxx_out' output is used to control the IO cell output value: 'xxx_out' is '0' to drive an IO cell output value of '0' and 'xxx_out' is '1' to drive an IO cell output value of '1'.
'1': Open drain operation mode. Typically this operation mode is used for IO cells that are connected to (board) wires/lines that are driven by multiple IO cells (possibly on multiple chips). In this operation mode, for and IO cell 'xxx' that is used as an output, the 'xxx_out_en' output controls the outputted value. Typically, open drain operation mode drives low/'0' and the 'xxx_out' output is constant '1'. In other words, in open drain operation mode, the 'xxx_out_en' output is used to control the IO cell output value: in drive low/'0' mode: 'xxx_out_en' is '1' (drive enabled) to drive an IO cell output value of '0' and 'xxx_out_en' is '1' (drive disabled) to not drive an IO cell output value (another IO cell can drive the wire/line or a pull up results in a wire/line value '1').
The open drain mode is supported for:
- I2C mode, 'i2c_scl' and 'i2c_sda' IO cells.
- UART mode, 'uart_tx' IO cell (SPI slave).
- SPI mode, 'spi_miso' IO cell.

DATA
Data read from the receiver FIFO. Reading a data frame will remove the data frame from the FIFO; i.e. behavior is similar to that of a POP operation. Note that when CTRL.BYTE_MODE is '1', only DATA[7:0] are used.
A read from an empty RX FIFO sets INTR_RX.UNDERFLOW to '1'.
When this register is read through the debugger, the data frame will not be removed from the FIFO. Similar in operation to RX_FIFO_RD_SILENT

AVG_CNT
Averaging Count for channels that have averaging enabled (AVG_EN). A channel will be sampled (1<<(AVG_CNT+1)) = [2..256] times.
- In ACCUNDUMP mode (1st order accumulate and dump filter) a channel will be sampled back to back, the average result is calculated and stored and then the next enabled channel is sampled. If shifting is not enabled (AVG_SHIFT=0) then the result is forced to shift right so that is fits in 16 bits, so right shift is done by max(0,AVG_CNT-3).
- In INTERLEAVED mode one sample is taken per triggered scan, only in the scan where the final averaging count is reached a valid average is calculated and stored in the RESULT register (by definition the same scan for all the channels that have averaging enabled). In all other scans the RESULT register for averaged channels will have an invalid result and the intermediate accumulated value is stored in the 16-bit WORK register. In this mode make sure that the averaging count is low enough to ensure that the intermediate value does not exceed 16-bits otherwise the MSBs will be lost. So for a 12-bit resolution the averaging count should be set to 16 or less (AVG_CNT=<3).

UAB_SCAN_MODE
Select whether UABs are scheduled or unscheduled. When no UAB is scanned this selection is ignored.
[22:22]
read-write
UNSCHEDULED
Unscheduled UABs: one or more of the UABs scanned by the SAR is not scheduled, for each channel that scans a UAB the SAR will wait for a positive edge on the trigger output of that UAB. Caveat: in this mode the length of SAR scan can be variable.
0
SCHEDULED
Scheduled UABs: All UABs scanned by the SAR are assumed to be properly scheduled, i.e. their output is assumed to be valid when sampled by the SAR and the SAR does not wait. In this mode the length of the SAR scan is constant.
This mode requires that the SAR scans strictly periodically, i.e. the SAR has to either run continuously or has to be triggered by a periodic hardware trigger (TCPWM or UDB timer). It also requires that the end of the UAB valid phase is precisely aligned with the end of the SAR sample period (using UAB.STARTUP_DELAY). Normally this scheduling is done by Creator.
1
REPEAT_INVALID
For unscheduled UAB_SCAN_MODE only, do the following if an invalid sample is received:

[19:0]
read-only
INTRLV_BUSY
If high then the SAR is in the middle of Interleaved averaging spanning several scans. While this bit is high the Firmware should not make any changes to the configuration registers otherwise some results may be incorrect. Note that the CUR_AVG_CNT status register below gives an indication how many more scans need to be done to complete the Interleaved averaging.
This bit can be cleared by changing the averaging mode to ACCUNDUMP or by disabling the SAR.
[23:23]
read-only
CUR_AVG_CNT
the current value of the averaging counter. Note that the value shown is updated after the sampling time and therefore runs ahead of the accumulator update.

When set to '1', the serial data will be transmitted 0.5 SCK cycles earlier than when set to '0'.
1) TX_CTL.SCKI_POL=0 and TX_CTL.B_CLOCK_INV=0: Serial data will be transmitted off the SCK falling edge
2) TX_CTL.SCKI_POL=0 and TX_CTL.B_CLOCK_INV=1: Serial data will be transmitted off the SCK rising edge that is 0.5 SCK cycles before the SCK falling edge in 1)
3) TX_CTL.SCKI_POL=1 and TX_CTL.B_CLOCK_INV=0: Serial data will be transmitted off the SCK rising edge
4) TX_CTL.SCKI_POL=1 and TX_CTL.B_CLOCK_INV=1: Serial data will be transmitted off the SCK falling edge that is 0.5 SCK cycles before the SCK rising edge in 3)
(Note that this is only the appearance w.r.t. SCK edge, the actual timing is generated by an internal clock that runs 8x the SCK frequency). The word sync (TX_WS) signal is not affected by this bit setting.
