General Call Address Recognition Flag
This bit is valid in slave receive mode.
[Setting condition]
•
[Clearing condition]
•
Set a unique address in bits SVA6 to SVA0, differing from
the addresses of other slave devices connected to the I
bus.
This bit is readable/writable. The write value should always
be 0.
