DREQ Level Activation Timing (Normal Mode): Set the DTA bit for the channel for which the DREQ pin is selected to
1.
Figure 7-25 shows an example of DREQ level activated normal mode transfer.
DREQ pin sampling is performed every cycle, with the rising edge of the next ø cycle after the end of the DMABCR write
cycle for setting the transfer enabled state as the starting point.
When the DREQ pin low level is sampled while acceptance by means of the DREQ pin is possible, the request is held in
the DMAC. Then, when activation is initiated in the DMAC, the request is cleared. After the end of the write cycle,
acceptance resumes, DREQ pin low level sampling is performed again, and this operation is repeated until the transfer
ends.

Figure 7-25 Example of DREQ Level Activated Normal Mode Transfer
Acceptance after transfer enabling; the DREQ pin low level is sampled on the rising
edge of ø, and the request is held.
The request is cleared at the next bus break, and activation is started in the DMAC.
The DMA cycle is started.
Acceptance is resumed after the write cycle is completed.
(As in [1], the DREQ pin low level is sampled on the rising edge of ø, and the request is held.)
