SS—Sub System Identifiers Register (LPC I/F—D31:F0)
Offset Address: 2Ch
Default Value:
This register is initialized to logic 0 by the assertion of PLTRST#. This register can be
written only once after PLTRST# de-assertion.
PMBASE—ACPI Base Address Register (LPC I/F—D31:F0)
Offset Address: 40h
Default Value:
Lockable:
Sets base address for ACPI I/O registers, GPIO registers and TCO I/O registers. These
registers can be mapped anywhere in the 64-K I/O space on 128-byte boundaries.

Subsystem ID (SSID) — R/WO This is written by BIOS. No hardware action taken on
this value.
Subsystem Vendor ID (SSVID) — R/WO This is written by BIOS. No hardware action
taken on this value.
Reserved
Base Address — R/W. This field provides 128 bytes of I/O space for ACPI, GPIO, and
TCO logic. This is placed on a 128-byte boundary.
Reserved
Resource Type Indicator (RTE) — RO. Hardwired to 1 to indicate I/O space.
