Register Name:
Access Type:
• WKMODE0: Wake-up Mode 0
• CPTWK0: Counter on Wake-up 0
Defines the number of 16 Slow Clock cycles, the level detection on the corresponding input pin shall last before the wake-
up event occurs. Because of the internal synchronization of WKUP0, the SHDN pin is released
(CPTWK x 16 + 1) Slow Clock cycles after the event on WKUP.
• RTTWKEN: Real-time Timer Wake-up Enable
0 = The RTT Alarm signal has no effect on the Shutdown Controller.
1 = The RTT Alarm signal forces the de-assertion of the SHDN pin.
• RTCWKEN: Real-time Clock Wake-up Enable
0 = The RTC Alarm signal has no effect on the Shutdown Controller.
1 = The RTC Alarm signal forces the de-assertion of the SHDN pin.
