Arbitration Lost Flag/Overrun Error Flag
This flag indicates that arbitration was lost in master
mode with the I
When two or more master devices attempt to seize the
bus at nearly the same time, if the I
detects data differing from the data it sent, it sets AL to 1
to indicate that the bus has been taken by another
master.

[Clearing condition]
•
When no acknowledge is detected from the receive
device in transmission while the ACKE bit in ICIER is
1
When 0 is written in NACKF after reading NACKF = 1
In master mode: when a stop condition is detected
after frame transfer is completed
In slave mode: when a stop condition is detected after
the address set in SAR matches the salve address
that comes as the first byte after the detection of a
start condition
When 0 is written in STOP after reading STOP = 1
If the internal SDA and SDA pin disagree at the rise of
SCL in master transmit mode
When the SDA pin outputs high in master mode while
a start condition is detected
When 0 is written in AL/OVE after reading AL/OVE =
