Warm RESET. Writing a `1' causes nRESET to be asserted. Writing `0' has no effect.
HOTSYNC interrupt Mask. When reads,
0 = Disable Hotsync interrupt from External pin.
1 = Enable Hotsync interrupt from External pin.
No External Power Interrupt Mask. When reads,
0 = Disable PMU interrupt from PMADAPOK LOW.
1 = Enable PMU interrupt from PMADAPOK LOW.
RTCEvt Interrupt Mask. When reads,
0 = Disable PMU interrupt from RTC
1 = Enable PMU interrupt from RTC
RIEvt Interrupt MASK PMU Interrupt Request / Clear
When reads,
0 = Disable PMU interrupt from MRING
1 = Enable PMU interrupt from MRING
OnEvt Interrupt MASK PMU Interrupt Enable
When reads,
0 = Disable PMU interrupt from nPMWAKEUP
1 = Enable PMU interrupt from nPMWAKEUP
HOTSYNC Event
When reads, 0 = Not Hot Sync state; 1 = Hot Sync status
When writes, HotSync Interrupt Clear. Writing a `1' to this bit clears the event bit
WDTEvt: Watch Dog Reset (Warm reset)
When reads,
0 = No Watch dog Timer event occured
1 = A Watch dog timer event has ocurred since last cleared
When writes, Watch dog Reset Clear. Writing a `1' to this bit clears the event bit
RESETEvt: Warm RESET Event (debounced)
When reads,
0 = No Warm RESET event has occurred
1 = A Warm RESET event has occurred since last cleared
When writes, Warm Reset Clear. Writing a `1' to this bit clears the event bit.
PowerFailEvt: ADPATOR NOT OK (debounced)
When reads,
0 = No Power Fail event since last cleared
1 = A Power Fail event has occurred since last cleared
When writes, Power Fail Interrupt Clear. Writing a `1' to this bit clears a pending interrupt bit.
RTCEvt
When reads,
0 = No Real Time Clock (RTC) calendar wake-up event since last cleared
1 = Real Time Clock (RTC) calendar wake-up event since last cleared
When writes, RTC Interrupt Clear. Writing a `1' to this bit clears a pending interrupt bit.
RIEvt (debounced)
When reads,
0 = No Modem Ring Indicate wake-up event since last cleared
1 = Modem Ring Indicate wake-up event since last cleared
When writes, RI Interrupt Clear. Writing a `1' to this bit clears a pending interrupt bit.

When writes to these bits, PMU
Interrupts will be enabling. `1' enables
interrupts to the CPU, `0' masks such
activity. Should the enable bit be set
to one when one of the debounced
event signals is set, then an interrupt
WILL be generated (i.e. the interrupt
is level sensitive, not edge sensitive).
