Enable staging S3, S4, or S5 state waiting for Stop Grant. When set the
power management unit will wait for the stop grant cycles before transi-
tioning into the S3, S4, or S5 state.

Enable staging S1 sleep state waiting for Stop Grant When set the power
management unit will wait for the stop grant cycles before transitioning
into the S1 state.

THRM_POL. H_THRM# Polarity. When set, active LOW H_THRM# asser-
tion sets the THRM_STS bit. When Clear, active HIGH H_THRM# assertion
sets the THRM_STS bit.

BIOS_RLS. BIOS Release. When set, an SCI will be generated and GBL_STS
bit will be set, if enabled by the GBL_EN bit. When Clear, no SCI or clear
of GBL_STS. This bit is used by BIOS software to raise an event to the
ACPI software.

SMI_EN. SMI Enable. When set, SMI# is generated upon any enabled
SMI# event. This bit is cleared by a P_RST#.

External RTC alarm/interrupt enable. When set, IRQ8 and the
RTC events in power management are routed from
GPIO_VAUX[15]. GPIO_VAUX[15] must be enabled as input
only for this to function.

Suspend from Mechanical Off. Determines the state that the
system will enter from mechanical off. If set, the system will
enter S5 state. If clear, the system will enter S0 state.
