21.3.20 TCD Minor Byte Count (Minor Loop Disabled)
TCD word 2's register definition depends on the status of minor loop mapping. If minor
loop mapping is disabled (CR[EMLM] = 0), TCD word 2 is defined as follows. If minor
loop mapping is enabled, see the TCD_NBYTES_MLOFFNO and
TCD_NBYTES_MLOFFYES register descriptions for TCD word 2's register definition.
Addresses: 4000_8000h base + 1008h offset + (32d × n), where n = 0d to 15d

Minor Byte Transfer Count
Number of bytes to be transferred in each service request of the channel. As a channel activates, the
appropriate TCD contents load into the eDMA engine, and the appropriate reads and writes perform until
the minor byte transfer count has transferred. This is an indivisible operation and cannot be halted.
(Although, it may be stalled by using the bandwidth control field, or via preemption.) After the minor count
