Mode
BACK_UP The main battery is not present or its voltage is too low but back-up battery voltage is
adequate and the 32 kHz oscillator is running (RTC is on).
PWR_OFF In this mode (warm), the main battery is present and its voltage is over N2300 BETTY
master reset threshold. All regulators are disabled, PurX is on low state, the RTC is on
and the oscillator is on. PWR_OFF (cold) mode is almost the same as PWR_OFF (warm),
but the RTC and the oscillator are off.
RESET RESET mode is a synonym for start-up sequence. RESET mode uses 32 kHz clock to count
the REST mode delay (typically 16ms).
SLEEP SLEEP mode is entered only from PWR_ON mode with the aid of SW when the system's
activity is low.
FLASHING FLASHING mode is for SW downloading.
