DESCRIPTION
PROPERTIES
RESET
31:0
Address Trapped by SMI or general-purpose trap. For an enabled trap,
this is the address that was present on the PCI bus.

ADDRESS: 74h-77h
SYMBOL: TRAP_DATA
BITS
DESCRIPTION
PROPERTIES
RESET
31:0
Data Trapped by SMI or general-purpose trap. For an enabled trap, this is
the data that was present on the PCI bus. This field is ignored if function
0, register 78h bit 9 is set.
R/W
0
Trap Command (Device 7h, Function 0h)
ADDRESS: 78h-79h
SYMBOL: TRAP_CMD

9
Enable SMI Trap to be a retry. When set with SMI trap and an enabled
trap, the result of the south bridge trapping the access will be a retry
with an SMI driven to the processor if enabled.
R/W
0
8
Enable SMI Trap. When set the south bridge will drive SMI for an enabled
trap and will fast decode the transaction and provide a response. The
address, data, byte enables, and command for the transaction will be
stored in TRAP_ADDR, TRAP_DATA, and TRAP_CMND. The following reg-
isters define enabled traps: DEVSTS, DEVCTL, GPAR1, and GPAR0.
R/W
0
7:4
BE Trapped for SMI or general-purpose trap. For an enabled trap, this is
the byte enable field that was present on the PCI bus.
R/W
0
3:0
Command Trapped for SMI or general-purpose trap. For an enabled trap,
this is the command field that was present on the PCI bus.
