In single address mode, both the transfer source and the transfer destination are external; one is
accessed by the DACK signal and the other by an address. In this mode, the DMAC performs a
DMA transfer in one bus cycle by simultaneously outputting the external device strobe signal
(DACK) to either the transfer source or transfer destination external device to access it, while
outputting an address to the other side of the transfer. Figure 11.6 shows an example of a
transfer between external memory and an external device with DACK in which the external
device outputs data to the data bus and that data is written to external memory in the same bus
cycle.
