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.
