Section 7 DMA Controller (DMAC)
ETCRAL is decremented by 1 each time a byte or word transfer is performed. In response to a
single transfer request, burst transfer is performed until the value in ETCRAL reaches H'00.
ETCRAL is then loaded with the value in ETCRAH. At this time, the value in the MAR register
for which a block designation has been given by the BLKDIR bit in DMACRA is restored in
accordance with the DTSZ, SAID/DAID, and SAIDE/DAIDE bits in DMACR.
