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 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]
•
When ICDR is written to (transmit mode) or read
from (receive mode)
•
When 0 is written in AAS after reading AAS = 1
•
In master mode

General Call 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 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]
•
When ICDR is written to (transmit mode) or read
from (receive mode)
•
When 0 is written in ADZ after reading ADZ = 1
•
In master mode
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).
