Description
Arbitration Lost Flag/Overrun Error Flag
Indicates that arbitration was lost in master mode with
the I
received while RDRF = 1 with the clocked synchronous
format.
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 occupied by another
master.

Slave Address Recognition Flag
In slave receive mode, this flag is set to 1 if the first
frame following a start condition matches bits SVA[6:0]
in SAR.
