Access:
• FWUPEN: Force Wake Up Enable
0 (NOT_ENABLE) = the Force Wake Up pin has no wake up effect.
1 (ENABLE) = the Force Wake Up pin low forces the wake up of the core power supply.
• SMEN: Supply Monitor Wake Up Enable
0 (NOT_ENABLE) = the supply monitor detection has no wake up effect.
1 (ENABLE) = the supply monitor detection forces the wake up of the core power supply.
• RTTEN: Real Time Timer Wake Up Enable
0 (NOT_ENABLE) = the RTT alarm signal has no wake up effect.
1 (ENABLE) = the RTT alarm signal forces the wake up of the core power supply.
• RTCEN: Real Time Clock Wake Up Enable
0 (NOT_ENABLE) = the RTC alarm signal has no wake up effect.
1 (ENABLE) = the RTC alarm signal forces the wake up of the core power supply.
