(3) The priorities of channels and DMA transfer timing
If a DMA transfer request signal falls on a single sampling cycle (a sampling cycle means one period from
the leading edge to the trailing edge of BCLK), the DMA request bits of applicable channels concurrently
turn to “1”. If the channels are active at that moment, DMA0 is given a high priority to start data transfer.
When DMA0 finishes data transfer, it gives the bus right to the CPU. When the CPU finishes single bus
access, then DMA1 starts data transfer and gives the bus right to the CPU.
An example in which DMA transfer is carried out in minimum cycles at the time when DMA transfer
request signals due to external factors concurrently occur.
