Value
R/W Description
4 AASX 0 R/(W)
*
Second Slave Address Recognition Flag
In I
2
C bus format slave receive mode, this flag is set to 1 if
the first frame following a start condition matches bits
SVAX6 to SVAX0 in SARX.
[Setting condition]
When the second slave address is detected in slave
receive mode and FSX = 0 in SARX
[Clearing conditions]
•
When 0 is written in AASX after reading AASX = 1
•
When a start condition is detected
•
In master mode
3 AL
0 R/(W)
*
Arbitration
Lost
Flag
Indicates that arbitration was lost in master mode.
[Setting conditions]
When ALSL=0
•
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 mode
When ALSL=1
•
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
2
C bus interface drives the SDA pin low, after the
start condition instruction was executed in master
transmit mode
[Clearing conditions]
•
When ICDR is written to (transmit mode) or read from
(receive mode)
•
When 0 is written in AL after reading AL = 1
