Bit 1—General Call Address Recognition Flag (ADZ): In I
this flag is set to 1 if the first frame following a start condition is the general call address (H'00).
ADZ is cleared by reading ADZ after it has been set to 1, then writing 0 in ADZ. In addition, ADZ
is reset automatically by write access to ICDR in transmit mode, or read access to ICDR in receive
mode.
