DMA_ES field descriptions (continued)
Field Description
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.
1
SBE
Source Bus Error
0 No source bus error
1 The last recorded error was a bus error on a source read
0
DBE
Destination Bus Error
0 No destination bus error
1 The last recorded error was a bus error on a destination write
21.3.3 Enable Request Register (DMA_ ERQ )
The ERQ register provide s a bit map for the 16 implemented channels to enable the
request signal for each channel. The state of any given channel enable is directly affected
by writes to this register; it is also affected by writes to the SERQ and CERQ. The
{S,C}ERQ registers are provided so the request enable for a single channel can easily be
modified without needing to perform a read-modify-write sequence to the ERQ .
