7.4
All DMAC functions on four channels are common. Each mode can be set independently for each
channel. The DMAC functions can be used by combining each function.

In single address mode, a transfer request from the on-chip USB
is not available.
(Transfer mode variations are the same as in dual address mode
except for a transfer request from the on-chip USB.)
Operation
Transfer Modes
Direct data transfer to/from external device using DACK pin
instead of source or destination address register
Above transfer mode can be specified in addition to address
register setting
