GPA1R. Capture reads enable. When set, the south bridge will observe
the address, data, byte enables, and command for a read transaction
that falls into the General Purpose Trap Address 1 (GPTA1) and store
them in TRAP_ADDR, TRAP_DATA, and TRAP_CMND. The address, status,
and space type is defined in GPAR1. The address bits to be masked as
part of the trap are defined in DEVCTL. The trap will be performed inde-
pendent of whether SMI traps are enabled in general or if the SMI trap is
enabled for GPTA1.

GPA0R. Capture writes enable. When set, the south bridge will observe
the address, data, byte enables, and command for a write transaction
that falls into the General Purpose Trap Address 1 (GPTA0) and store
them in TRAP_ADDR, TRAP_DATA, and TRAP_CMND. The address, status,
and space type is defined in GPAR0. The address bits to be masked as
part of the trap are defined in DEVCTL. The trap will be performed inde-
pendent of whether SMI traps are enabled in general or if the SMI trap is
enabled for GPTA0.
