Figure 7.33 shows an example of single address transfer using the write data buffer function. In
this example, the CPU program area is in on-chip memory.
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.
7.5.12
The DMAC channel priority order is: channel 0 > channel 1, and channel A > channel B. Table
7.11 summarizes the priority order for DMAC channels.
