Section 8 DMA Controller (DMAC)
resumes after the end of the single cycle, DREQ pin low level sampling is performed again, and
this operation is repeated until the transfer ends.
DREQ Pin Low Level Activation Timing: Set the DTA bit in DMABCRH to 1 for the channel
for which the DREQ pin is selected.
Figure 8.32 shows an example of single address mode transfer activated by the DREQ pin low
level.
