RTC Event Enable (RTC_EN) — R/W. This bit is in the RTC well to allow an RTC event to wake
after a power failure. This bit is not cleared by any reset other than RTCRST# or a Power Button
Override event.
0 = No SCI (or SMI#) or wake event is generated then RTC_STS goes active.
1 = An SCI (or SMI#) or wake event will occur when this bit is set and the RTC_STS bit goes
Reserved.
Power Button Enable (PWRBTN_EN) — R/W. This bit is used to enable the setting of the
PWRBTN_STS bit to generate a power management event (SMI#, SCI). PWRBTN_EN has no
effect on the PWRBTN_STS bit being set by the assertion of the power button. The Power Button is
always enabled as a Wake event.
0 = Disable.
1 = Enable.
Reserved.
Global Enable (GBL_EN) — R/W. When both the GBL_EN and the GBL_STS are set, an SCI is
raised.
0 = Disable.
1 = Enable SCI on GBL_STS going active.
Reserved.
Timer Overflow Interrupt Enable (TMROF_EN) — R/W. Works in conjunction with the SCI_EN bit
