Arbitration Lost Flag
This flag indicates that arbitration was lost in master
mode.
When two or more master devices attempt to seize
the bus at nearly the same time, if the I
interface detects data differing from the data it sent,
it sets AL to 1 to indicate that the bus has been taken
by another master.
[Setting conditions]
•
•
[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.
When a stop condition is detected after frame
transfer.
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 after reading AL =1.
