Initial Value R/W
0
R/(W) * I
Description
Indicates that the I
request to the CPU.
IRIC is set at different times depending on the FS bit in
SAR, the FSX bit in SARX, and the WAIT bit in ICMR. See
section 16.4.7, IRIC Setting Timing and SCL Control. The
conditions under which IRIC is set also differ depending on
the setting of the ACKE bit in ICCR.

C Bus Interface Interrupt Request Flag
C bus format master mode:
C bus format slave mode:
When a start condition is detected in the bus line state
after a start condition is issued (when the ICDRE flag is
set to 1 because of first frame transmission)
When a wait is inserted between the data and
acknowledge bit when the WAIT bit is 1 (fall of the 8th
transmit/receive clock)
At the end of data transfer (rise of the 9th
transmit/receive clock while no wait is inserted)
When a slave address is received after bus arbitration
is lost (the first frame after the start condition)
If 1 is received as the acknowledge bit (when the ACKB
bit in ICSR is set to 1) when the ACKE bit is 1
When the AL flag is set to 1 after bus arbitration is lost
while the ALIE bit is 1
When the slave address (SVA or SVAX) matches
(when the AAS or AASX flag in ICSR is set to 1) and at
the end of data transfer up to the subsequent
retransmission start condition or stop condition
detection (rise of the 9th transmit/receive clock)
When the general call address is detected (when 0 is
received as the R/W bit and the ADZ flag in ICSR is set
to 1) and at the end of data reception up to the
subsequent retransmission start condition or stop
condition detection (rise of the 9th receive clock)
If 1 is received as the acknowledge bit (when the ACKB
bit in ICSR is set to 1) while the ACKE bit is 1
When a stop condition is detected (when the STOP or
ESTP flag in ICSR is set to 1) while the STOPIM bit is 0
