20.7 DMA Channel Priorities
that has the higher priority always takes precedence.
generated in a transfer cycle, DMA transfer on the channel with the lower priority is executed after the bus is released
to the CPU (the new transfer request for the same channel is ignored in the transfer cycle).
770
The DMA channel priorities are fixed as follows.
When the DMAC has released the bus, if another DMA transfer request that has a higher priority is issued, the one
If a new transfer request for the same channel and a transfer request for another channel with a lower priority are
The priorities are checked for every transfer cycle.
DMA0 transfer request
DMA1 transfer request
DMA2 transfer request
DMA3 transfer request
DMA channel 0 > DMA channel 1 > DMA channel 2 > DMA channel 3
If multiple DMA transfer requests are acknowledged at the same time, transfer is executed from the one with
the higher priority.
Note The CPU is using the bus, or the bus is unused.
