Executing channels are allowed to complete. Channel execution resumes when the system exits debug mode or the EDBG bit is cleared. #1 ERCA Enable Round Robin Channel Arbitration 2 1 read-write 0 Fixed priority arbitration is used for channel selection . #0 1 Round robin arbitration is used for channel selection . #1 HOE Halt On Error 4 1 read-write 0 Normal operation #0 1 Any error causes the HALT bit to set. Subsequently, all service requests are ignored until the HALT bit is cleared. #1 HALT Halt DMA Operations 5 1 read-write 0 Normal operation #0 1 Stall the start of any new channels. Executing channels are allowed to complete. Channel execution resumes when this bit is cleared. #1 CLM Continuous Link Mode 6 1 read-write 0 A minor loop channel link made to itself goes through channel arbitration before being activated again. #0 1 A minor loop channel link made to itself does not go through channel arbitration before being activated again. Upon minor loop completion, the channel activates again if that channel has a minor loop channel link enabled and the link channel is itself. This effectively applies the minor loop offsets and restarts the next minor loop. #1 EMLM Enable Minor Loop Mapping 7 1 read-write 0 Disabled. TCDn.word2 is defined as a 32-bit NBYTES field. #0 1 Enabled. TCDn.word2 is redefined to include individual enable fields, an offset field, and the NBYTES field. The individual enable fields allow the minor loop offset to be applied to the source address, the destination address, or both. The NBYTES field is reduced when either offset is enabled. #1 ECX Error Cancel Transfer 16 1 read-write 0 Normal operation #0 1 Cancel the remaining data transfer in the same fashion as the CX bit. Stop the executing channel and force the minor loop to finish. The cancel takes effect after the last write of the current read/write sequence. The ECX bit clears itself after the cancel is honored. In addition to cancelling the transfer, ECX treats the cancel as an error condition, thus updating the Error Status register (DMAx_ES) and generating an optional error interrupt. #1 CX Cancel Transfer 17 1 read-write 0 Normal operation #0 1 Cancel the remaining data transfer. Stop the executing channel and force the minor loop to finish. The cancel takes effect after the last write of the current read/write sequence. The CX bit clears itself after the cancel has been honored. This cancel retires the channel normally as if the minor loop was completed. #1 ES Error Status Register 0x4 32 read-only 0 0xFFFFFFFF DBE Destination Bus Error 0 1 read-only 0 No destination bus error #0 1 The last recorded error was a bus error on a destination write #1 SBE Source Bus Error 1 1 read-only 0 No source bus error #0 1 The last recorded error was a bus error on a source read #1 SGE Scatter/Gather Configuration Error 2 1 read-only 0 No scatter/gather configuration error #0 1 The last recorded error was a configuration error detected in the TCDn_DLASTSGA field. This field is checked at the beginning of a scatter/gather operation after major loop completion if TCDn_CSR[ESG] is enabled. TCDn_DLASTSGA is not on a 32 byte boundary. #1 NCE NBYTES/CITER Configuration Error 3 1 read-only 0 No NBYTES/CITER configuration error #0 1 The last recorded error was a configuration error detected in the TCDn_NBYTES or TCDn_CITER fields. TCDn_NBYTES is not a multiple of TCDn_ATTR[SSIZE] and TCDn_ATTR[DSIZE], or TCDn_CITER[CITER] is equal to zero, or TCDn_CITER[ELINK] is not equal to TCDn_BITER[ELINK] #1 DOE Destination Offset Error 4 1 read-only 0 No destination offset configuration error #0 1 The last recorded error was a configuration error detected in the TCDn_DOFF field. TCDn_DOFF is inconsistent with TCDn_ATTR[DSIZE]. #1 DAE Destination Address Error 5 1 read-only 0 No destination address configuration error #0 1 The last recorded error was a configuration error detected in the TCDn_DADDR field. TCDn_DADDR is inconsistent with TCDn_ATTR[DSIZE]. #1 SOE Source Offset Error 6 1 read-only 0 No source offset configuration error #0 1 The last recorded error was a configuration error detected in the TCDn_SOFF field. TCDn_SOFF is inconsistent with TCDn_ATTR[SSIZE]. #1 SAE Source Address Error 7 1 read-only 0 No source address configuration error. #0 1 The last recorded error was a configuration error detected in the TCDn_SADDR field. TCDn_SADDR is inconsistent with TCDn_ATTR[SSIZE]. #1 ERRCHN Error Channel Number or Canceled Channel Number 8 4 read-only CPE Channel Priority Error 14 1 read-only 0 No channel priority error #0 1 The last recorded error was a configuration error in the channel priorities . Channel priorities are not unique. #1 ECX Transfer Canceled 16 1 read-only 0 No canceled transfers #0 1 The last recorded entry was a canceled transfer by the error cancel transfer input #1 VLD
