General-Purpose Status 1 Register 3 (GPE1_STS_3)

This register contains bits 24-31 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.

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 9.3.16 and 9.3.17 on pages 193ff.):

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 Key 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 9.3.17 on page 194). Writing ‘1’ clears this bit; writing ‘0’ is

ignored.

0: Inactive since last cleared (default)

1: A mouse event occurred

RI2_EVT_STS (RI2 Event Status). Indicates that a telephone ring signal was received at Serial Port 2 and the

event was identiﬁed by the RI Wake-up Detector. This bit is set by a high-to-low transition at the RI2 pin (see

Section 9.2.1 on page 162). 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 2

RI1_EVT_STS (RI1 Event Status). Indicates that a telephone ring signal was received at Serial Port 1 and the

event was identiﬁed by the RI Wake-up Detector. This bit is set by a high-to low transition at the RI1 pin (see

Section 9.2.1 on page 162). 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 1
