EDREQ Pin Low Level Activation Timing: Figure 8.27 shows an example of single address
mode transfer activated by the EDREQ pin low level.
EDREQ pin sampling is performed in each cycle starting at the next rise of after the end of the
EDMDR write cycle for setting the transfer-enabled state.
When a low level is sampled at the EDREQ pin while acceptance via the EDREQ pin is possible,
the request is held within the EXDMAC. Then when activation is initiated within the EXDMAC,
the request is cleared. At the end of the single cycle, acceptance resumes and EDREQ pin low
level sampling is performed again; this sequence of operations is repeated until the end of the
transfer.

[2], [5] Request is cleared at end of next bus cycle, and activation is started in EXDMAC.
[3], [6] DMA cycle is started.
[4], [7] Acceptance is resumed after completion of single cycle.
Acceptance after transfer enabling; EDREQ pin low level is sampled at rise of , and request is held.
(As in [1], EDREQ pin low level is sampled at rise of , and request is held.)
