Description
Stop Condition Detection Flag
[Setting condition]
•
[Clearing condition]
•
Arbitration Lost 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, the I
SDA. If it detects data differing from the data it sent, it sets
the AL flag to 1 to indicate that the bus has been taken by
another master.
[Setting conditions]

[Clearing condition]
•
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.

[Clearing condition]
•
When a stop condition is detected after frame transfer
When 0 is written to STOP after reading STOP = 1
If the internal SDA and SDA pin does not match at the
rise of SCL in master transmit mode
When the SDA pin goes high in master mode while a
start condition is detected
When 0 is written to AL after reading AL = 1
When the slave address is detected in slave receive
mode
When the general call address is detected in slave
receive mode
When 0 is written to AAS after reading AAS = 1
