Description
In I
first frame following a start condition matches bits SVAX6 to
SVAX0 in SARX.
[Setting condition]
[Clearing conditions]
Indicates that arbitration was lost in master mode.
[Setting conditions]
When ALSL = 0
When ALSL = 1

When the second slave address is detected in slave receive
mode and FSX = 0 in SARX
When 0 is written in AASX after reading AASX = 1
When a start condition is detected
In master mode
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
bus interface drives the SDA pin low, after the start condition
instruction was executed in master transmit mode
When ICDR is written to (transmit mode) or read from
(receive mode)
When 0 is written in AL after reading AL = 1
C bus format slave receive mode, this flag is set to 1 if the
