The Analog Comparator Interface (ACIFA) is able to control two Analog Comparators (AC) with
identical behavior. An Analog Comparator compares two voltages and gives a compare output
depending on this comparison.
The ACIFA can be configured in normal mode (see
mode (see
The AC’s Inputs are programmable between internal inputs (DAC, voltage reference, ...) and
external input pins.
According to the comparison result, each comparator can trigger a separate interrupt in normal
mode. In window function, an additional interrupt can be triggered, depending if the voltage to be
compared is inside or outside the window.
The ACIFA is able to generate two output events that can be used through PEVC to trigger a
hardware process.
