14.3.4
The DMAC supports the transfers shown in table 14.5. The dual address mode comprises the
direct address mode and 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. The data transfer
timing differs depending on the bus mode. The bus mode comprises the cycle steal mode and burst
mode.

Address Mode:
• Dual Address Mode
In the dual address mode, the transfer source and destination are accessed by addresses. Both
external and internal addresses can be used for the transfer source or destination. The dual address
mode consists of the direct address transfer mode (1) and indirect address transfer mode (2).
2. Single: Single address mode
3. The dual address mode includes the direct address mode and the indirect address
4. 16-byte transfer is not available for on-chip supporting modules.
