Table 8-4. EDMA_ESR field descriptions
Field Description
VLD Valid Bit
Logical OR of all EDMA_ERL status bits.
0 No EDMA_ER bits are set.
1 At least one EDMA_ER bit is set indicating a valid error exists that has not been cleared.
ECX Transfer canceled
0 No canceled transfers
1 The last recorded entry was a canceled transfer via the error cancel transfer input.
GPE Group-priority error
0 No group-priority error
1 The last recorded error was a configuration error among the group priorities indicating not all
group priorities are unique.
CPE Channel-Priority Error
0 No channel-priority error
1 The last recorded error was a configuration error in the channel priorities within a group,
indicating not all channel priorities within a group are unique.
ERRCHN Error Channel Number or Canceled Channel Number
Channel number of the last recorded error (excluding GPE and CPE errors) or last recorded transfer
that was error cancelled.
Note: Do not rely on the number in the ERRCHN field group for channel-priority errors. Group- and
Channel-priority errors must be resolved by inspection. The application code must interrogate
the priority registers to find groups or channels with duplicate priority level.
SAE Source Address Error
0 No source address configuration error
1 The last recorded error was a configuration error detected in field EDMA_TCD[SADDR],
indicating EDMA_TCD[SADDR] is inconsistent with EDMA_TCD[SSIZE].
SOE Source Offset Error
0 No source offset configuration error
1 The last recorded error was a configuration error detected in field EDMA_TCD[SOFF], indicating
EDMA_TCD[SOFF] is inconsistent with EDMA_TCD[SSIZE].
