When the write data buffer function is activated, the DMAC recognizes that the bus cycle concerned has ended, and starts
the next operation. Therefore, DREQ pin sampling is started one state after the start of the DMA write cycle or single
address transfer.

The DMAC channel priority order is: channel 0 > channel 1, and channel A > channel B. Table 7-13 summarizes the
priority order for DMAC channels.
