3.1.1 AC

Analog Comparator

3.1.1.1 Introduction

The Analog Comparator (AC) module compares the voltage levels on two inputs and gives a digital output based on this comparison. The AC can be configured to generate interrupt requests and/or events based on several different combinations of input change. The input selection includes analog port pins and internally generated inputs. The AC digital output goes through controller logic, enabling customization of the signal for use internally with the Event System or externally on the pin.

3.1.1.2 Supported Device Families
