This register contains bits 24-31 of the GPE1_EN register. This register belongs to the General-Purpose Event 1 Group of
the ACPI fixed-feature space registers.
The enable bits behave according to the Enable Bit definition (the bit is read/write by software) in the ACPI Specification.

Description
7
SW_OFF_EN (Software Off Event Enable).
Enables the event of the software writing a ‘1’ to the
SW_OFF_CTL bit in the SWC_CTL register to generate a power management interrupt (SIOSCI).
0: Disable SCI (default)
1: Enable SCI from the software writing a ‘1’ to the SW_OFF_CTL bit in the SWC_CTL register
6
SW_ON_EN (Software On Event Enable).
Enables the event of the software writing a ‘1’ to the SW_ON_CTL
bit in the SWC_CTL register to generate a power management interrupt (SIOSCI).
0: Disable SCI (default)
1: Enable SCI from the software writing a ‘1’ to the SW_ON_CTL bit in the SWC_CTL register
5
WDO_EVT_EN (Watchdog Event Enable).
Enables an watchdog time-out event to generate a power
management interrupt (SIOSCI).
0: Disable SCI (default)
1: Enable SCI from watchdog time-out
4
MOD_IRQ_EN (Modules IRQ Event Enable).
Enables an active IRQ from one of the Legacy modules or from
the XIRQ pin (
PC87413 and PC87417
) to generate a power management interrupt (SIOSCI).
0: Disable SCI (default)
1: Enable SCI by an active IRQ from one of the Legacy modules or from the XIRQ pin
3
MS_IRQ_EN (Mouse IRQ Event Enable).
Enables an IRQ generated by the mouse interface section of the
KBC module to generate a power management interrupt (SIOSCI).
0: Disable SCI (default)
1: Enable SCI from an IRQ generated by the mouse interface section of the KBC module
2
KBD_IRQ_EN (Keyboard IRQ Event Enable).
Enables an IRQ generated by the keyboard interface section of
the KBC module to generate a power management interrupt (SIOSCI).
0: Disable SCI (default)
1: Enable SCI from an IRQ generated by the keyboard interface section of the KBC module
1
P12_EVT_EN (Port P12 Event Enable).
Enables an IRQ by an active high signal generated at the P12 pin to
generate a power management interrupt (SIOSCI).
0: Disable SCI (default)
1: Enable SCI from an active high signal generated at the P12 pin
0
RTC_EVT_EN (RTC Alarm Event Enable).
Enables an RTC alarm to generate a power management interrupt
(SIOSCI). This bit is similar to the RTC_EN bit in the PM1b_EN_HIGH register. It should be enabled only if the
system does not support the PM1b_EVT register block.
0: Disable SCI (default)
1: Enable SCI from RTC alarm
