Section 8 EXDMA Controller (EXDMAC)
(2)
Figure 8.16 shows an example of transfer when ETEND output is enabled, and word-size, normal
transfer mode (burst mode) is performed from external 16-bit, 2-state access space to external 16-
bit, 2-state access space.
In burst mode, one-byte or one-word transfers are executed continuously until transfer ends.
Once burst transfer starts, requests from other channels, even of higher priority, are held pending
until transfer ends.
If an NMI interrupt is generated while a channel designated for burst transfer is enabled for
transfer, the EDA bit is cleared and transfer is disabled. If a block transfer has already been
initiated within the EXDMAC, the bus is released on completion of the currently executing byte or
word transfer, and burst transfer is aborted. If the last transfer cycle in burst transfer has been
initiated within the EXDMAC, transfer is executed to the end even if the EDA bit is cleared.
