When the NRD bit is set to 1 in EDMDR, the acceptance timing of the next transfer request can be
delayed one cycle later.
Figure 11.38 shows an example of single address mode transfer activated by the EDREQ pin low
level with NRD = 1 specified.
EDREQ pin sampling is performed in each cycle starting at the next rise of Bφ after the end of the
DTE bit write cycle.
When a low level is sampled at the EDREQ pin while acceptance of a transfer request 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. After the end of the single cycle, acceptance resumes
when one cycle of the request clearance period specified by NRD = 1 expires and EDREQ pin low
level sampling is performed again. This sequence of operations is repeated until the end of the
transfer.

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