Bit Bit Name
Initial
Value R/W Description
4 NAKIE 0 R/W NACK Receive Interrupt Enable
This bit enables or disables the NACK receive interrupt
request (NAKI) and the overrun error (setting of the OVE
bit in ICSR) interrupt request (ERI) with the clocked
synchronous format, when the NACKF and AL bits in
ICSR are set to 1. NAKI can be canceled by clearing the
NACKF, 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
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 Judgement 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.
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.
