General-Purpose Status 1 Register 2 (GPE1_STS_2)

This register contains bits 16-23 of the GPE1_STS register. This register belongs to the General-Purpose Event 1 Group of

the ACPI fixed-feature space registers.

The status bits behave according to the Sticky status bit definition (the bit is set by the HIGH level of the hardware signal

and is only cleared by the software writing ‘1’ to it) in the ACPI Specification.

Power Well:VSB

Location: Offset 02h

Type:

R/W1C

Bit

Description

GPIOE47_STS (GPIOE47 Event Status). Indicates that an active event has been detected at pin 7 of the

GPIOE Port 4. The event has programmable polarity and the debounce option (see Section 7.3.1 on page 137).

The bit is set by an active level at the GPIOE47 pin. Writing ‘1’ clears this bit; writing ‘0’ is ignored.

0: Inactive since last cleared (default)

1: An active event has occurred

6-0

GPIOE46_STS to GPIOE40_STS (GPIOE46 to GPIOE40 Event Status). Same as above for pins 6-0 of the

GPIOE Port 4.

Bit

Description

PWBT_EVT_STS (Power Button Event Status). Indicates that the Power button was pressed. This bit is similar

to the PWRBTN_STS bit in the PM1b_STS_HIGH register. The PWBTIN signal is internally debounced. Writing

‘1’ clears this bit and the PWRBTN_STS bit in the PM1b_STS_HIGH register; writing ‘0’ is ignored. This bit is

also cleared in Legacy Power Button mode (LEGACY_PWBT = 1 in PWONCTL) when VDD is turned off by

pressing the Power button.

0: Inactive (default)

1: The Power button was pressed

SLBT_EVT_STS (Sleep Button Event Status). Indicates that the Sleep button was pressed. This bit is similar

to the SLPBTN_STS bit in the PM1b_STS_HIGH register. The SLBTIN signal is internally debounced. Writing

‘1’ clears this bit and the SLPBTN_STS bit in the PM1b_STS_HIGH register; writing ‘0’ is ignored.

0: Inactive (default)

1: The Sleep button was pressed

KBD_EVT3_STS (Keyboard Event 3 Status). Indicates that “PM Key 3” was pressed and that the event was

identiﬁed by the Keyboard/Mouse Wake-up Detector. This bit is set only if the Keyboard/Mouse Wake-up

Detector is in the Power Management Key mode (see Section 9.3.16 on page 193). Writing ‘1’ clears this bit;

writing ‘0’ is ignored.

0: Inactive since last cleared (default)

1: The “PM Key 3” key was pressed on the keyboard

KBD_EVT2_STS (Keyboard Event 2 Status). Indicates that “PM Key 2” was pressed and that the event was

identiﬁed by the Keyboard/Mouse Wake-up Detector. This bit is set only if the Keyboard/Mouse Wake-up

Detector is in the Power Management Key mode (see Section 9.3.16 on page 193). Writing ‘1’ clears this bit;

writing ‘0’ is ignored.

0: Inactive since last cleared (default)

1: The “PM Key 2” key was pressed on the keyboard
