Bus arbitration won
Cleared when ICDR data is written (transmit mode) or read (receive mode)
Cleared by reading AL = 1, then writing 0
Arbitration lost
Set if the internal SDA and bus line disagree at the rise of SCL in master transmit mode
Set if the internal SCL is high at the fall of SCL in master transmit mode
General Call Address Recognition Flag

1
Slave address or general call address not recognized (Initial value)
Cleared when ICDR data is written (transmit mode) or read (receive mode)
Cleared by reading AAS = 1, then writing 0
Slave address or general call address recognized
Set when the slave address or general call address is detected in slave receive mode
General call address not recognized
Cleared when ICDR data is written (transmit mode) or read (receive mode)
