Receive Acknowledge
Transmit Acknowledge
Description
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
0: Stop condition detection interrupt request
1: Stop condition detection interrupt request

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
In receive mode, this bit specifies the bit to be sent
at the acknowledge timing.
