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
1: Transfer direction: External device with
counter are disabled
counter are enabled
device with DACK
DACK→ EDDAR
