Information
DMA_ES field descriptions (continued)
Field Description
15
Reserved
This read-only field is reserved and always has the value zero.
14
CPE
Channel Priority Error
0 No channel priority error
1 The last recorded error was a configuration error in the channel priorities. Channel priorities are not
unique.
13–12
Reserved
This read-only field is reserved and always has the value zero.
11–8
ERRCHN
Error Channel Number or Cancelled Channel Number
The channel number of the last recorded error (excluding CPE errors) or last recorded error cancelled
transfer.
7
SAE
Source Address Error
0 No source address configuration error.
1 The last recorded error was a configuration error detected in the TCDn_SADDR field. TCDn_SADDR
is inconsistent with TCDn_ATTR[SSIZE].
6
SOE
Source Offset Error
0 No source offset configuration error
1 The last recorded error was a configuration error detected in the TCDn_SOFF field. TCDn_SOFF is
inconsistent with TCDn_ATTR[SSIZE].
5
DAE
Destination Address Error
0 No destination address configuration error
1 The last recorded error was a configuration error detected in the TCDn_DADDR field. TCDn_DADDR
is inconsistent with TCDn_ATTR[DSIZE].
4
DOE
Destination Offset Error
0 No destination offset configuration error
1 The last recorded error was a configuration error detected in the TCDn_DOFF field. TCDn_DOFF is
inconsistent with TCDn_ATTR[DSIZE].
3
NCE
NBYTES/CITER Configuration Error
0 No NBYTES/CITER configuration error
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]
2
SGE
Scatter/Gather Configuration Error
0 No scatter/gather configuration error
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.
