Description
NACK Receive Interrupt Enable
This bit enables or disables the NACK receive
interrupt request (NAKI) when the NACKF and AL
bits in ICSR are set to 1. NAKI can be canceled by
clearing the NACKF, AL, or NAKIE bit to 0.
0: NACK receive interrupt request (NAKI) is
1: NACK receive interrupt request (NAKI) is
Stop Condition Detection Interrupt Enable
0: Stop condition detection interrupt request
1: Stop condition detection interrupt request
Acknowledge Bit Judgement Select
0: The value of the acknowledge bit is ignored,

Receive Acknowledge
In transmit mode, this bit stores the acknowledge
data that are returned by the receive device. This
bit cannot be modified.
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.
