Description
7
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
6
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
5
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
4
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
3
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
2
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
1
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
0
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
