case, either a 1 or a 0 value are acceptable on the incoming slave address. Additionally, if the GC bit in
register SMB0ADR is set to 1, hardware will recognize the General Call Address (0x00). Table 26.4 shows
some example parameter settings and the slave addresses that will be recognized by hardware under
those conditions.
