Gpe0_En-General Purpose Event 0 Enables Register - Intel 6300ESB Datasheet

8.8.3.8 GPE0_EN—General Purpose Event 0 Enables Register
Note: This register is symmetrical to the General Purpose Event 0 Status Register. All the bits
in this register should be cleared to 0 based on a Power Button Override. The resume
well bits are all cleared by RSMRST#. The RTC well bits are cleared by RTCRST#.

Description
These bits enable the corresponding GPI[n]_STS bits being
set to cause a SCI, and/or wake event. These bits are cleared
by RSMRST#.
Reserved.
Enables the setting of the PME_B0_STS bit to generate a
wake event and/or an SCI or SMI#. PME_B0_STS may be a
wake event from the S1-S4 states, or from S5 (when entered
through SLP_TYP and SLP_EN) or power failure, but not
Power Button Override. This bit defaults to 0. It is only
cleared by Software or RTCRST#. It is not cleared by CF9h
writes.
Reserved.
This bit defaults to 0. It is only cleared by Software or
RTCRST#. It is not cleared by CF9h writes.
0 = Disable.
1 = Enables the setting of the PME_STS to generate a wake
event and/or an SCI. PME# may be a wake event from
the S1 - S4 state or from S5 (when entered through
SLP_EN or power failure, but not power button override).
Reserved.
Reserved.
The value of this bit will be maintained through a G3 state
and is not affected by a hard reset caused by a CF9h write.
0 = Disable.
1 = Enables the setting of the RI_STS to generate a wake
event.
Reserved.
0 = Disable.
1 = Enables the setting of the TCOSCI_STS to generate an
SCI.
0 = Disable.
1 = Enables the setting of the AC97_STS to generate a wake
event.
