[Setting condition]
When a stop condition is detected after frame transfer
[Clearing condition]
When 0 is written in STOP after reading STOP = 1

When two or more master devices attempt to seize the bus
at nearly the same time, if the I
differing from the data it sent, it sets AL to 1 to indicate that

•
When the SDA pin outputs high in master mode while a
start condition is detected
[Clearing condition]
When 0 is written in AL/OVE after reading AL/OVE=1
R/W Slave Address Recognition Flag
In slave receive mode, this flag is set to 1 if the first frame
following a start condition matches bits SVA6 to SVA0 in
SAR.
[Setting conditions]
•
When the slave address is detected in slave receive
mode
•
When the general call address is detected in slave
receive mode.
[Clearing condition]
When 0 is written in AAS after reading AAS=1
