Slave Address Recognition Flag
Description
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, the I2C bus monitors
SDA, and if the I2C bus 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.
[Setting conditions]
•
•
[Clearing condition]
•
In slave receive mode, this flag is set to 1 when the first
frame following a start condition matches bits SVA6 to
SVA0 in SAR.
[Setting conditions]
•
•
[Clearing condition]
•
When the internal SDA and the SDA pin level
disagree at the rising of SCL in master transmit
mode
When the SDA pin outputs a high level in master
mode while a start condition is detected
When 0 is written to this bit after reading AL = 1
(When the CPU is used to clear this flag by writing
0 while the corresponding interrupt is enabled, be
sure to read the flag after writing 0 to it.)
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 this bit after reading AAS = 1
