Flag
The IRTR flag indicates that the I
generated an interrupt for the CPU at the end of
transmission and reception one frame of data. The IRIC
flag is set to 1 at the same time as the IRTR flag is set to 1.

C Bus Interface Continuous Transfer Interrupt Request
Detection of the stop condition during the transfer of
one frame
Writing of 0 to this bit after reading ESTP = 1
Clearing of the IRIC flag to 0
Detection of the stop condition after the transfer of one
frame
Writing of 0 to this bit after reading STOP = 1
Clearing of the IRIC flag to 0
Setting of the ICDRE or ICDRF flag to 1 while AASX is
1 in the I
Setting of the ICDRE or ICDRF flag to 1, when in
master mode in I2C bus interface or synchronous serial
format
Writing of 0 to this bit after reading IRTR = 1
Clearing of the IRIC flag to 0 with ICE = 0
