R/(W)* Slave Address Recognition Flag
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]

0
R/(W)* General Call Address Recognition Flag
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).

C bus format slave receive mode, this flag is set to 1 if
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
