In this 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 24.4
shows some example parameter settings and the slave addresses that will be recognized by hardware
under those conditions.

Table 24.4. Hardware Address Recognition Examples (EHACK = 1)
SMBus Hardware Slave Address.
Defines the SMBus Slave Address(es) for automatic hardware acknowledgement.
Only address bits which have a 1 in the corresponding bit position in SLVM[6:0]
are checked against the incoming address. This allows multiple addresses to be
recognized.
General Call Address Enable.
When hardware address recognition is enabled (EHACK = 1), this bit will deter-
mine whether the General Call Address (0x00) is also recognized by hardware.
0: General Call Address is ignored.
1: General Call Address is recognized.
