R/(W) * Slave Address Recognition Flag
R/(W) * General Call Address Recognition Flag
Description
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]
In I
the first frame following a start condition is the general call
address (H'00).
[Setting condition]
When the general call address (one frame including a R/W
bit is H'00) is detected in slave receive mode and FS = 0 or
FSX = 0
[Clearing conditions]
If a general call address is detected while FS = 1 and FSX
= 0, the ADZ flag is set to 1; however, the general call
address is not recognized (AAS flag is not set to 1).
