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
