Description
NACK Receive Interrupt Enable
This bit enables or disables the NACK detection
interrupt request (IINAKI) and the overrun error (OVE
set in ICSR) interrupt request (IIERI) in the clock
synchronous format when the NACKF or AL/OVE bit in
ICSR is set. IINAKI can be canceled by clearing the
NACKF, AL/OVE, or NAKIE bit to 0.
0: NACK receive interrupt request (IINAKI) is disabled.
1: NACK receive interrupt request (IINAKI) is enabled.
Stop Condition Detection Interrupt Enable
This bit enables or disables the stop condition detection
interrupt request (IISTPI) when the STOP bit in ICSR is
set.
0: Stop condition detection interrupt request (IISTPI) is
1: Stop condition detection interrupt request (IISTPI) is

Receive Acknowledge
In transmit mode, this bit stores the acknowledge data
that are returned by the receive device. This bit cannot
be modified. This bit can be canceled by setting the
BBSY bit in ICCR2 to 1.
0: Receive acknowledge = 0
1: Receive acknowledge = 1
Transmit Acknowledge
In receive mode, this bit specifies the bit to be sent at
the acknowledge timing.
0: 0 is sent at the acknowledge timing.
1: 1 is sent at the acknowledge timing.
