Section 8 EXDMA Controller (EXDMAC)
(3)
In external request mode, an EXDMA transfer cycle is started a minimum of three cycles after a
transfer request is accepted. The next transfer request is accepted after the end of a one-transfer-
unit EXDMA cycle. For external bus space CPU cycles, at least two bus cycles are generated
before the next EXDMA cycle.
If a transfer request is generated for another channel, an EXDMA cycle for the other channel is
generated before the next EXDMA cycle.
The EDREQ pin sensing timing is different for low level sensing and falling edge sensing. The
same applies to transfer request acceptance and transfer start timing.
Figures 8.35 to 8.38 show operation timing examples for various conditions.
