9.4.4 DMA Transfer Types
The DMAC supports the transfers shown in table 9.4. The dual address mode has the direct
address mode and the indirect address mode. In the direct address mode, an output address value
is the data transfer target address; in the indirect address mode, the value stored in the output
address, not the output address value itself, is the data transfer target address. A data transfer
timing depends on the bus mode, which has cycle steal mode and burst mode.
