11.4.4
The DMAC supports the types of transfer shown in table 11.7. 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.
