SLP_TYP - Defines the type of hardware sleeping state the
system enters when the SLP_EN bit is set. This field may also
be used by BIOS and OS to determine the type of sleep state
the system is resuming from.

GBL_RLS. Global Release. This bit is used by ACPI software to
raise event to BIOS software by generating SMI# and passing
execution control to the BIOS. BIOS software has correspond-
ing enable and status bits to control its ability to receive ACPI
events. The GBL_RLS bit is set by ACPI driver to indicate a
release of the global lock and the setting of the pending bit
in the FACS memory structure.

BM_RLD. Bus Master Reload Enable. When Set, this bit allows
generation of a bus master request to cause any processor in
the C3 state to transition to C0 state. When clear, bus master
request has no effect on processors in C3 state.

SCI_EN. SCI Enable. Selects whether power management
events in the PM1 Fixed Feature register and General Purpose
0 register generate an SCI or SMI#. When set, SCI is selected.
When clear, SMI# is selected.
