CHAPTER 1

GENERAL INFORMATION

1.1 INTRODUCTION

This manual provides general information, hardware preparation, installation instructions, monitor

program description, operating instructions, hardware description, and support information for

the M68HC11 Evaluation Board (EVB).

Downloading S-record information is contained in Appendix A. While a listing of the EVB

monitor program is stored on the diskettes supplied with the EVB (see file buf25.asm). (This file

may be viewed using any text reader capable of handling a 123K file.)

NOTE

Unless otherwise specified, all address references are in

hexadecimal throughout this manual.

An asterisk (*) following the signal name denotes that the signal is

true or valid when the signal is low.

1.2 FEATURES

EVB features include:

• An economical means of debugging user assembled code and evaluating target systems

incorporating MC68HC11 microcomputer unit (MCU) device

• One-line assembler/disassembler

• Host computer downloading capability

• MC68HC11 MCU based debugging/evaluating circuitry

• MC68HC24 Port Replacement Unit (PRU) based MCU I/O expansion circuitry

• MC6850 Asynchronous Communications Interface Adapter (ACIA) based terminal

I/O port circuitry

• RS-232C compatible terminal/host computer I/O ports
