DMACR is a 16-bit readable/writable register that controls the operation of each DMAC channel. In full address mode,
DMACRA and DMACRB have different functions.
DMACR is initialized to H'0000 by a reset, and in hardware standby mode.
DMACRA
DMACRB
Bit 15—Data Transfer Size (DTSZ): Selects the size of data to be transferred at one time.
Bit 14—Source Address Increment/Decrement (SAID)
Bit 13—Source Address Increment/Decrement Enable (SAIDE): These bits specify whether source address register
MARA is to be incremented, decremented, or left unchanged, when data transfer is performed.
Bit 12—Block Direction (BLKDIR)

When DTSZ = 0, MARA is incremented by 1 after a transfer
When DTSZ = 1, MARA is incremented by 2 after a transfer
When DTSZ = 0, MARA is decremented by 1 after a transfer
When DTSZ = 1, MARA is decremented by 2 after a transfer
