Revision 1.2

6.4.6

General-Purpose Status 1 Register 2 (GPE1_STS_2)

This register contains “child” events 16-23 of the GPE1_STS register.

The status bits behave according to the Sticky status bit definition in the ACPI Specification (i.e., the bit is set when the level

of the hardware signal is high and is only cleared by the software writing 1 to it).

Description

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 Power Management Keys mode (see Section 6.3.6 on page 82). 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 Power Management Keys mode (see Section 6.3.6 on page 82). 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

KBD_EVT1_STS (Keyboard Event 1 Status). This bit indicates that a keyboard event occurred and was

identiﬁed by the Keyboard/Mouse Wake-Up Detector. The event type depends on the selected operation mode

for the Keyboard/Mouse Wake-Up Detector (see Sections 6.3.6 and 6.3.7 on page 82.):

Pressing any key or a sequence of special keys in Special Key Sequence mode

Pressing a sequence of keys in Password mode

Pressing the “PM Key 1” in Power Management Keys mode

Writing 1 clears this bit; writing 0 is ignored.

0: Inactive since last cleared (default)

1: A keyboard event occurred

MS_EVT_STS (Mouse Event Status). Indicates that a mouse event occurred and was identiﬁed by the

Keyboard/Mouse Wake-Up Detector (see Section 6.3.7 on page 83). Writing 1 clears this bit; writing 0 is ignored.

0: Inactive since last cleared (default)

1: A mouse event occurred

KBD_ANYK_STS (Keyboard Any-Key Status). This bit indicates that any key 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 Fast Any-Key mode (see Section 6.3.6 on page 82). Writing 1 clears this bit; writing 0 is ignored.

0: Inactive since last cleared (default)

1: A keyboard event occurred

RI_EVT_STS (RI Event Status). Indicates that a telephone ring signal was received at the Serial Port and the

event was identiﬁed by the RI Wake-Up Detector. This bit is set by a high-to-low transition at the RI pin (see

Section 6.2.1 on page 71). Writing 1 clears this bit; writing 0 is ignored.

0: Inactive since last cleared (default)

1: A telephone ring signal was received at the Serial Port
