RESET
31:2
Address. Programmable trap address. Address compare to the appropri-
ate space type may issue a SCI or SMI#.
R/W
0
1
Status. When set, indicates that the programmed transaction has caused
a trap.
R/WOTC
0
Space type. Programmable trap address type. When set, the address
space is I/O. When clear, the address space is memory.

DESCRIPTION
PROPERTIES
RESET
31:8
Device Trap Enable. When set, enable trap SMI# generation when access
to device defined in corresponding bit of DEVSTS occurs. When clear,
trap SMI# is disabled.
R/W

8Reserved.
R/W
0
7:5
Mask address bit 5:3 for General Programmable Address 1. When a bit is
set, that address bit will be ignored in determining a match.
R/W
0
4
Enable Trap of General Programmable Address 1. When set a cycle on
the PCI bus matching the General Purpose Address Trap 1 will set Global
Programmable Address Space Status in DEVSTS and will be trapped by
the LPC PCI target and H_SMI# will be driven active if enabled in DEVSTS.
R/W

Enable Trap of General Programmable Address 0. When set a cycle on
the PCI bus matching the General Purpose Address Trap 0 will set Global
Programmable Address Space Status in DEVSTS and will be trapped by
the LPC PCI target and H_SMI# will be driven active if enabled in DEVSTS.
