Section 14 Direct Memory Access Controller (DMAC)
14.3.4
The DMAC supports the transfers shown in table 14.6. It can operate in single address mode, in
which either the transfer source or the transfer destination is accessed using the acknowledge
signal, or in dual address mode, in which both the transfer source and transfer destination
addresses are output. The actual transfer operation timing depends on the bus mode, which can be
either burst mode or cycle steal mode.
