Description
Interrupt Request Flag
Flag indicating that an interrupt request has
occurred and transfer has ended.
0: No interrupt request
[Clearing conditions]

Transfer Counter End Interrupt Enable
Enables or disables transfer end interrupt requests
by the transfer counter. When transfer ends
according to the transfer counter while this bit is set
to 1, the IRF bit is set to 1, indicating that an
interrupt request has occurred.
0: Transfer end interrupt requests by transfer
1: Transfer end interrupt requests by transfer
Single Address Direction
Specifies the data transfer direction in single
address mode. In dual address mode, the
specification by this bit is ignored.
0: Transfer direction: EDSAR → external device
1: Transfer direction: External device with DACK→
