15.6 Cautions on Using DMA Controller
594
(1) Priority of DMA
During DMA transfer, a request from the other DMA channel is held pending even if generated. The pending
DMA transfer is started after the ongoing DMA transfer is completed. If two DMA requests are generated at
the same time, however, DMA channel 0 takes priority over DMA channel 1.
If a DMA request and an interrupt request are generated at the same time, the DMA transfer takes
precedence, and then interrupt servicing is executed.
