The Analog Comparator compares the input values on the positive pin (AIN1) and negative pin
(AIN0). When the voltage on the positive pin is higher than the voltage on the negative pin, the
Analog Comparator output, ACO, is set. The comparator can trigger a separate interrupt, exclu-
sive to the Analog Comparator. The user can select Interrupt triggering on comparator output
rise, fall or toggle. A block diagram of the comparator and its surrounding logic is shown in
