Arbitration Lost Flag/Overrun Error Flag
This flag indicates that arbitration was lost in master
mode with the I
been 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 taken by another
master.
[Clearing condition]
[Setting conditions]
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 the final bit is received with the clocked
synchronous format while RDRF = 1
When 0 is written in AL/OVE after reading AL/OVE=1
2
C bus format and that the final bit has
