Figure 8-24 shows an example of

DREQ

pin falling edge activated block transfer mode transfer.

Note: In write data buffer mode, bus breaks from [2] to [7] may be hidden, and not visible.

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.
Start of DMA cycle;

DREQ

pin high level sampling on the rising edge of ø starts.

When the

DREQ

pin high level has been sampled, acceptance is resumed after the dead cycle

is completed.
(As in [1], the

DREQ

pin low level is sampled on the rising edge of ø, and the request is held.)

Figure 8-24 Example of

DREQ

Pin Falling Edge Activated Block Transfer 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, and

DREQ

pin high level sampling for edge detection is started. If

DREQ

high level sampling has been completed by the time the DMA dead cycle ends, acceptance
resumes after the end of the dead cycle,

DREQ

pin low level sampling is performed again, and this

operation is repeated until the transfer ends.
