Bit Bit Name
Initial
Value R/W Description
4 NAKIE 0 R/W NACK Receive Interrupt Enable
Enables or disables the NACK detection and arbitration
lost/overrun error interrupt request (NAKI) when NACKF
or AL/OVE in ICSR is set to 1. NAKI can be canceled
by clearing the NACKF, AL/OVE, or NAKIE bit to 0.
0: NACK receive interrupt request (NAKI) is disabled.
1: NACK receive interrupt request (NAKI) is enabled.
3 STIE 0 R/W Stop Condition Detection Interrupt Enable
Enables or disables the stop condition detection
interrupt request (STPI) when the STOP bit in ICSR is
set.
0: Stop condition detection interrupt request (STPI) is
disabled.
1: Stop condition detection interrupt request (STPI) is
enabled.
2 ACKE 0 R/W Acknowledge Bit Judgment Select
0: The value of the receive acknowledge bit is ignored,
and continuous transfer is performed.
1: If the receive acknowledge bit is 1, continuous
transfer is halted.
1 ACKBR 0 R 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
0 ACKBT 0 R/W 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.
