Intel® 460GX Chipset Software Developer's Manual
Slave Enable (SLV_EN)–R/W. 1 = Enable the generation of an interrupt or resume event upon
an external SMBus master generating a transaction with an address that matches the host
controller slave port of 10h, a command field which matches the SMBSLVC register, and a
match of one of the corresponding enabled events in the SMBSLVEVT register. 0 = Disable.

SMBus Shadow Command Register (I/O)
Base + (09h)
00h
Read only
Shadow Command (SHDW_CMD)–RO. This field contains the command value which was
received during an external SMBus master access whose address field matched the host slave
address (10h) or one of the slave shadow port addresses.
–
SMBus Slave Event Register (I/O)
Base + (0Ah)
0000h
Read/Write
SM BUS Slave Event (SMB_SLV_EVT)–R/W. This field contains data bits used to compare
against incoming data to the SMBSLVDAT register. When a bit in this register is a 1 and the
corresponding bit in the SMBSLVDAT register is set, then an interrupt or resume event will be
generated if the command value matches the value in the SMBSLVC register and the access
was to SMBus host address 10h.
Base + (0Ch)
0000h
Read only
SLAVE DATA (SMB_SLV_DATA)–RO. This field contains the data value which was transmitted
during an external SMBus master access whose address field matched one of the slave shadow
port addresses or the SMBus host controller slave port address of 10h.
