14.3.3 Destination Address Registers (DAR0–DAR3)
DARn, shown in
14.3.4 Byte Count Registers (BCR0–BCR3) and DMA Status
BCRn, shown in
BCRn decrements on the successful completion of the address transfer of a write transfer. BCRn
decrements by 1, 2, 4, or 16 for byte, word, longword, or line accesses, respectively.

The DMA does not maintain coherency with the cache. Therefore,
DMAs should not transfer data to cacheable memory unless software
is used to maintain the cache coherency.
