Section 14 Direct Memory Access Controller (DMAC)
Auto request, external request, and peripheral module request are available for the transfer request.
DACK can be output in read cycle or write cycle in dual address mode. CHCR can specify
whether the DACK is output in read cycle or write cycle.
Figure 14.5 shows an example of DMA transfer timing in dual address mode.
