9.4.8
This register contains bits 0-7 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.

This register contains bits 8-15 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.

SLP_TYPx (Sleep Type).
This field defines the system sleep state type (encoded). The states
supported by the PC8741x devices are: Working (G0/S0), Sleeping (G1/S1-S4) and Soft-off (G2/S5).
The encoding of the sleep state is programmed through the V
PP
-powered registers S0_SLP_TYP to
S5_SLP_TYP.

Description
7
GPIOE17_STS (GPIOE17 Event Status).
Indicates that an active event has been detected at pin 7 of the
GPIOE Port 1. 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 GPIOE17 pin. Writing ‘1’ clears this bit; writing ‘0’ is ignored.
0: Inactive since last cleared (default)
1: An active event has occurred
6-0
GPIOE16_STS to GPIOE10_STS (GPIOE16 to GPIOE10 Event Status).
Same as above for pins 6-0 of the
GPIOE Port 1.
