10.4
Table 10.4 shows the DMAC transfer modes. The transfer modes can be specified to the
individual channels.
Table 10.4 Transfer Modes
When the auto request setting is selected as the activation source, the cycle stealing or burst access
can be selected. When the total transfer size is not specified (DTCR = H'00000000), the transfer
counter is stopped and the transfer is continued without the limitation of the transfer count.

Repeat transfer
Block transfer
Instead of specifying the source or destination address
registers, data is directly transferred from/to the external
device using the DACK pin
The same settings as above are available other than address
register setting (e.g., above transfer modes can be specified)
One transfer can be performed in one bus cycle (the types of
transfer modes are the same as those of dual address modes)
