IRTR flag setting is performed when the TDRE or RDRF flag is set to 1. IRTR is cleared by
reading IRTR after it has been set to 1, then writing 0 in IRTR. IRTR is also cleared automatically
when the IRIC flag is cleared to 0.
Bit 4—Second Slave Address Recognition Flag (AASX): In I
this flag is set to 1 if the first frame following a start condition matches bits SVAX6 to SVAX0 in
SARX.
AASX is cleared by reading AASX after it has been set to 1, then writing 0 in AASX. AASX is
also cleared automatically when a start condition is detected.
