(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.
