DMACR is an 8-bit readable/writable register that controls the operation of each DMAC channel.
DMACR is initialized to H'00 by a reset, and in standby mode.
Bit 7—Data Transfer Size (DTSZ): Selects the size of data to be transferred at one time.

Bit 6—Data Transfer Increment/Decrement (DTID): Selects incrementing or decrementing of
MAR after every data transfer in sequential mode or repeat mode.
In idle mode, MAR is neither incremented nor decremented.

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