9.3.4
The DMAC supports the transfers shown in table 9.5. It can operate in the single address mode or
dual address mode, which are defined by how many bus cycles the DMAC takes to access the
transfer source and transfer destination. The actual transfer operation timing varies with the bus
mode. The DMAC has two bus modes: cycle-steal mode and burst mode.
