16.4.5.23.2 Function
One of three registers (this register, TCD_NBYTES_MLNO, or
TCD_NBYTES_MLOFFYES), defines the number of bytes to transfer per request.
Which register to use depends on whether minor loop mapping is disabled, enabled but
not used for this channel, or enabled and used.
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. If minor loop mapping is disabled,
then refer to the TCD_NBYTES_MLNO register description.

16.4.5.23.4 Fields
Field Function
31
SMLOE
Source Minor Loop Offset Enable
Selects whether the minor loop offset is applied to the source address upon minor loop completion.
0b - The minor loop offset is not applied to the SADDR
1b - The minor loop offset is applied to the SADDR
30
DMLOE
Destination Minor Loop Offset enable
Selects whether the minor loop offset is applied to the destination address upon minor loop completion.
0b - The minor loop offset is not applied to the DADDR
1b - The minor loop offset is applied to the DADDR
29-0
NBYTES
Minor Byte Transfer Count
Number of bytes to be transferred in each service request of the channel.
