to 1 to indicate that the bus has been taken by another master.
AL is cleared by reading AL after it has been set to 1, then writing 0 in AL. In addition, AL is
reset automatically by write access to ICDR in transmit mode, or read access to ICDR in receive
mode.

1. When 0 is written in AASX after reading AASX = 1
2. When a start condition is detected
3. In master mode
Second slave address recognized
[Setting condition]
When the second slave address is detected in slave receive mode while FSX = 0
