Bit

Description

PWBT_EVT_EN (Power Button Event Enable). Enables Power button pressing to generate a power

management interrupt (SIOSCI). This bit is similar to the PWRBTN_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 Power button pressing

SLBT_EVT_EN (Sleep Button Event Enable). Enables Sleep button pressing to generate a power

management interrupt (SIOSCI). This bit is similar to the SLPBTN_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 Sleep button pressing

KBD_EVT3_EN (Keyboard Event 3 Enable). Enables the event of pressing “PM Key 3” (on the keyboard) to

generate a power management interrupt (SIOSCI).

0: Disable SCI (default)

1: Enable SCI from pressing the “PM Key 3” on the keyboard

KBD_EVT2_EN (Keyboard Event 2 Enable). Enables the event of pressing “PM Key 2” (on the keyboard) to

generate a power management interrupt (SIOSCI).

0: Disable SCI (default)

1: Enable SCI from pressing the “PM Key 2” on the keyboard

KBD_EVT1_EN (Keyboard Event 1 Enable). Enables the event of pressing any key, key sequence or “PM Key

1” (on the keyboard) to generate a power management interrupt (SIOSCI).

0: Disable SCI (default)

1: Enable SCI from pressing a sequence of keys or the “PM Key 1” on the keyboard

MS_EVT_EN (Mouse Event Enable). Enables a mouse event identiﬁed by the Keyboard/Mouse Wake-up

Detector to generate a power management interrupt (SIOSCI).

0: Disable SCI (default)

1: Enable SCI from mouse event identified by the Keyboard/Mouse Wake-up Detector

RI2_EVT_EN (RI2 Event Enable). Enables a telephone ring received at the Serial Port 2 event, and identiﬁed

by the RI Wake-up Detector, to generate a power management interrupt (SIOSCI).

0: Disable SCI (default)

1: Enable SCI from telephone ring event received at the Serial Port 2

RI1_EVT_EN (RI1 Event Enable). Enables a telephone ring received at the Serial Port 1 event, and identiﬁed

by the RI Wake-up Detector, to generate a power management interrupt (SIOSCI).

0: Disable event (default)

1: Enable SCI from telephone ring event received at the Serial Port 1
