SAM3U Series
• SMOS: Supply Monitor Output Status
0 (HIGH) = the supply monitor detected VDDUTMI higher than its threshold at its last measurement.
1 (LOW) = the supply monitor detected VDDUTMI lower than its threshold at its last measurement.
• OSCSEL: 32-kHz Oscillator Selection Status
0 (RC) = the slow clock, SLCK is generated by the embedded 32-kHz RC oscillator.
1 (CRYST) = the slow clock, SLCK is generated by the 32-kHz crystal oscillator.
• FWUPIS: FWUP Input Status
0 (LOW) = FWUP input is tied low.
1 (HIGH) = FWUP input is tied high.
• WKUPIS0-WKUPIS15: WKUP Input Status 0 to 15
0 (DIS) = the corresponding wake-up input is disabled, or was inactive at the time the debouncer triggered a wake up
event.
1 (EN) = the corresponding wake-up input was active at the time the debouncer triggered a wake up event.
