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.
