This section describes the API for the MC56F83xx and MC56F80xx ADC on-chip module. The

functionality of the ADC module itself is described in the MC56F83xx Peripheral User

Manual, 56F8000 Peripheral Reference Manual and 56F802x/3x Peripheral Reference

Introduction

The MC56F83xx devices can have up to two ADC modules (ADC A and ADC B). The

MC56F80xx devices contains only one ADC_A module. The ADC module has 2x4 analog

inputs, configurable as single-ended or differential. It can be configured for simultaneous

sampling of the two inputs, for sequential scanning and storing of up to 8 measurements and for

various other options. The ADC module can be synchronized with a PWM and a QTimer module.

The ADC module can be powered down manually or automatically.

This section describes the Analog-to-Digital Converter driver software, which provides the lowest

level software layer, interfacing hardware with software.
