Description
This bit is valid in I
[Setting condition]
When a stop condition is detected during frame transfer.
[Clearing conditions]
This bit is valid in I
[Setting condition]
When a stop condition is detected after frame transfer
completion.
[Clearing conditions]
Flag
Indicates that the I
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.
[Setting conditions]

C Bus Interface Continuous Transfer Interrupt Request
C bus format slave mode:
When 0 is written in ESTP after reading ESTP = 1
When the IRIC flag in ICCR is cleared to 0
When 0 is written in STOP after reading STOP = 1
When the IRIC flag is cleared to 0
When the ICDRE or ICDRF flag in ICDR is set to 1
when AASX = 1
When the ICDRE or ICDRF flag is set to 1
When 0 is written after reading IRTR = 1
When the IRIC flag is cleared to 0 while ICE is 1
