Overview

The Analog Comparator (AC) compares the voltage level on two inputs and gives a digital output
based on this comparison. The Analog Comparator may be configured to give interrupt requests
and/or events upon several different combinations of input change.
Two important properties of the Analog Comparator when it comes to the dynamic behavior, are
hysteresis and propagation delay. Both these parameters may be adjusted in order to find the
optimal operation for each application.
The Analog Comparators are always grouped in pairs (AC0 and AC1) on each analog port. They
have identical behavior but separate control registers.
