DMA_TCDn_NBYTES_MLNO field descriptions (continued)
Field
Description
is exhausted, the SADDR and DADDR values are written back into the TCD memory, the major iteration
count is decremented and restored to the TCD memory. If the major iteration count is completed,
additional processing is performed.
NOTE: An NBYTES value of 0x0000_0000 is interpreted as a 4 GB transfer.
21.3.21 TCD Signed Minor Loop Offset (Minor Loop Enabled and
Offset Disabled) (DMA_TCD_NBYTES_MLOFFNO)
TCD word 2 is defined as follows if:
• Minor loop mapping is enabled (CR[EMLM] = 1) and
• SMLOE = 0 and DMLOE = 0
If minor loop mapping is enabled and SMLOE or DMLOE is set then refer to the
TCD_NBYTES_MLOFFYES register description.
Addresses: 4000_8000h base + 1008h offset + (32d × n), where n = 0d to 15d

Source Minor Loop Offset Enable
Description
Selects whether the minor loop offset is applied to the source address upon minor loop completion.
0 The minor loop offset is not applied to the SADDR
1 The minor loop offset is applied to the SADDR
Destination Minor Loop Offset enable
Selects whether the minor loop offset is applied to the destination address upon minor loop completion.
0 The minor loop offset is not applied to the DADDR
1 The minor loop offset is applied to the DADDR
Minor Byte Transfer Count
Number of bytes to be transferred in each service request of the channel.
