This bit is valid in I
[Setting condition]
[Clearing conditions]
Indicates that the IIC module has issued an interrupt request to
the CPU, and the source is completion of reception/transmission
of one frame in continuous transmission/reception for which DTC
activation is possible. When the IRTR flag is set to 1, the IRIC
flag is also set to 1 at the same time.

C Bus Interface Continuous Transfer Interrupt Request Flag
When a stop condition is detected during frame transfer.
When 0 is written in ESTP after reading ESTP = 1
When the IRIC flag in ICCR is cleared to 0
When a stop condition is detected during frame transfer.
When 0 is written in STOP after reading STOP = 1
When the IRIC flag in ICCR is cleared to 0
When the ICDRE or ICDRF flag in ICXR is set to 1 when
AASX = 1
When the ICDRE or ICDRF flag in ICXR is set to 1
When 0 is written in IRTR after reading IRTR = 1
When the IRIC flag in ICCR is cleared to 0 (while ICE = 1 or
ICXE = 1)
