Table 24.11. SMB0ADM Register Bit Descriptions
Function
SMBus0 Slave Address Mask.
Defines which bits of register SMB0ADR are compared with an incoming address byte,
and which bits are ignored. Any bit set to 1 in SLVM enables comparisons with the corre-
sponding bit in SLV. Bits set to 0 are ignored (can be either 0 or 1 in the incoming
address).
Hardware Acknowledge Enable.
Enables hardware acknowledgement of slave address and received data bytes.
0: Firmware must manually acknowledge all incoming address and data bytes.
1: Automatic slave address recognition and hardware acknowledge is enabled.
