DAC Driver

This section describes the API of MC56F802x/3x Digital-to-Analog Converter (DAC) on-chip

module. The functionality of the DAC module itself is described in the 56F802x/3x Peripheral

Reference Manual.

Introduction

The MC56F802x/3x devices have one or two DAC modules which can be used internally in the

device to set the Analog Comparator (CMP) threshold or a calibration voltage for Analog-

to-Digital Converter (ADC). On some devices (e.g. MC56F8037), the signals for DACs are also

available externally as a peripheral function of certain GPIO pins.

This section describes the DAC driver software, providing the low level software layer interfacing

hardware with software.

Quick Reference

This section is intended as a source of quick access information, while the details are discussed in
