R/(W) * Arbitration Lost Flag
R/(W) * Slave Address Recognition Flag
Description
Indicates that arbitration was lost in master mode.
[Setting conditions]
When ALSL = 0
When ALSL = 1
[Clearing conditions]
In I
the first frame following a start condition matches bits SVA6
to SVA0 in SAR, or if the general call address (H'00) is
detected.
[Setting condition]
When the slave address or general call address (one frame
including a R/W bit is H'00) is detected in slave receive
mode and FS = 0 in SAR
[Clearing conditions]

If the internal SDA and SDA pin disagree at the rise of
SCL in master transmit mode
If the internal SCL line is high at the fall of SCL in
master transmit mode
If the internal SDA and SDA pin disagree at the rise of
SCL in master transmit mode
If the SDA pin is driven low by another device before
the I
start condition instruction was executed in master

When 0 is written in AL after reading AL = 1
When ICDR is written to (transmit mode) or read from
