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.
