Description

PWBTOUT_MODE (PWBTOUT Mode). When reset, this bit enables the pulsing of the PWBTOUT pin whenever

an enabled wake-up event occurs.

0: PWBTOUT pulsed by (default):

— PWBTIN activation

— Crowbar condition

— Wake-Up events

1: PWBTOUT pulsed by:

— PWBTIN activation

— Crowbar condition

Reserved.

RTC_EV_DIS (RTC Event Disable). Disables the RTC alarm event to the PM1b_STS_HIGH and

PM1b_EN_HIGH, ACPI registers (RTC_STS = 0, RTC_EN = 0). However, the RTC_EVT_STS bit in the

GPE1_STS_3 register and the RTC_EVT_EN bit in the GPE1_EN_3 register are not affected.

0: Disable event (default)

1: Enable the RTC alarm event

SLPBTN_EV_DIS (Sleep Button Event Disable). Enables the Sleep button pressing event to the

PM1b_STS_HIGH and PM1b_EN_HIGH ACPI registers (SLPBTN_STS = 0, SLPBTN_EN = 0). The

SLBT_EVT_STS bit in the GPE1_STS_2 register and the SLBT_EVT_EN bit in the GPE1_EN_2 register are not

affected.

0: Disable event (default)

1: Enable Sleep button pressing event

PWRBTN_EV_DIS (Power Button Event Disable). Enables the Power button pressing event to the

PM1b_STS_HIGH and PM1b_EN_HIGH ACPI registers (PWRBTN_STS = 0, PWRBTN_EN = 0). The

PWBT_EVT_STS bit in the GPE1_STS_2 register and the PWBT_EVT_EN bit in the GPE1_EN_2 register are

not affected.

0: Disable event (default)

1: Enable Power button pressing event
