Goal: Monitor a voltage for a drop below a threshold value Without Analog Comparator Poll the ADC Loop: Read ADC value If below threshold, call handler Wait Branch to loop With Analog Comparator Use the comparator to trigger the ADC when needed, then interrupt the CPU when value read ADC AD...
The normal OVR (default) is triggered if the final 12bit data output exceeds the maximum code value. The fast OVR is triggered if the input voltage exceeds the programmable overrange threshold and is presented after just nine clock cycles, thus enabling a quicker reaction to an overrange event...
