1.2 Introduction

The Freescale MC68HC705MC4 microcontroller is a low-cost M68HC05

Family EPROM microcontroller intended for use in industrial motor

control and power supply applications. Features include a 2-channel,

8-bit, high-speed pulse-width modulator (PWM) module (including a

commutation multiplexer for brushless permanent magnet motor

control), a 6-input, 8-bit analog-to-digital (A/D) controller to

accommodate analog feedback signals, and a serial communications

interface (SCI) to support multi-controller networking.
