GPI_STS VCORE. GPI VCORE Status. Set with an enabled General Purpose
input event occurred in ACPI_BASE + A0h. When enabled with GPI_EN
VCORE, a SCI, SMI#, or wake event will be generated.

GPI_STS. GPI Status. Set with an enabled Standby General Purpose input
event occurred in ACPI_BASE + 54h or ACPI_BASE + 80h. When enabled
with GPI_EN, a SCI, SMI#, or wake event will be generated.

THRM_OVR_STS. Thermal Override Status. Set when H_THRM# is asserted
for 2 seconds and thermal clock throttling initiated. Remains cleared if
thermal clock throttling isn’t initiated. This bit generates an override
that starts throttling the CPU clock at the THRM_DTY cycle. When
enabled with THRM_OVR_EN, a SCI, SMI#, or wake event will be gener-
ated.

THRM_STS. Thermal Status. Set when H_THRM# asserted. Assertion level
is specified by THRM_POL bit. If the THRM_EN and THRM_STS bits are set
then a SCI, SMI#, or wake event will be generated.

USB_STS. USB Status. Set when USB resume (connect, disconnect, or USB
resume) has occurred. If the USB_EN and USB_STS bits are set then a SCI,
SMI#, or wake event will be generated.
R/WOTC

2
SMB_STS. SMB Status. Set when a SMB wake event (ALERT) is detected.
Typically this is used as a PME for motherboard components.

EXT_SMI_STS. External SMI Status. Set when a PWR_EXT_SMI# active
event is detected. Allowed to wake-up system in S1.
R/WOTC
0
PME_STS. PME Status. Set when P_PME# is asserted. If the PME_EN and
PME_STS bits are set then a SCI, SMI#, or wake event will be generated.
