When 0 is written in AASX after reading AASX = 1
When a start condition is detected
In master mode
If the internal SDA and SDA pin disagree at the
rise of SCL in master transmit mode
If the internal SCL line is high at the fall of SCL in
master transmit mode
If the internal SDA and SDA pin disagree at the
rise of SCL in master transmit mode
If the SDA pin is driven low by another device
before the I
low, after the start condition instruction was
executed in master transmit mode
When ICDR is written to (transmit mode) or read
from (receive mode)
When 0 is written in AL after reading AL = 1
C bus format slave receive mode, this flag is set to
2
