General-Purpose Enable 1 Register 3 (GPE1_EN_3)

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.

Bit

Description

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

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

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

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

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

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

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

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
