HSCMP Driver

This section describes the API of MC56F800x High Speed Analog Comparator (HSCMP)

on-chip module. The functionality of the HSCMP module itself is described in the 56F800x

Peripheral Reference Manual.

Introduction

The MC56F800x devices have three High Speed Analog Comparator modules. Each comparator

has up to eight external analog -input pins Four of these pins are positive input and four pins are

negative input High speed comparator. High speed comparator output can be windowed, sampled

and digitaly filtered. There is selectable interrupt on rising edge, falling edge or either rising or

falling edge of comparator output. Each HSCMP output can be conected to external pin

This section describes the HSCMP driver software, providing the low level software layer

interfacing hardware with software.
