14.7.3 Analog watchdog threshold control
LT[11:0] and HT[11:0] can be changed during an analog-to-digital conversion (that is
between the start of the conversion and the end of conversion of the ADC internal state). If
LT and HT bits are programmed during the ADC guarded channel conversion, the watchdog
function is masked for this conversion. This mask is cleared when starting a new
conversion, and the resulting new AWD threshold is applied starting the next ADC
conversion result. AWD comparison is performed at each end of conversion. If the current
ADC data are out of the new threshold interval, this does not generated any interrupt or an
ADC_AWD1_OUT signal. The Interrupt and the ADC_AWD1_OUT generation only occurs
at the end of the ADC conversion that started after the threshold update. If
ADC_AWD1_OUT is already asserted, programming the new threshold does not deassert
the ADC_AWD1_OUT signal.
