R/(W) * I
R/(W) * Second Slave Address Recognition Flag
Description
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.

I
Master mode or clocked synchronous serial format mode
with I
[Clearing conditions]
In I
the first frame following a start condition matches bits
SVAX6 to SVAX0 in SARX.
[Setting condition]
When the second slave address is detected in slave
receive mode and FSX = 0 in SARX

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
When 0 is written in AASX after reading AASX = 1
When a start condition is detected
