LAB 1

BJECTIVES

In this experiment you will:

• become familiar with the CMM332 board

• become familiar with the AxIDE assembler

• create an ASCII text ﬁle containing a simple MC68000 assembly language program

• establish a serial interface communication between a computer and the CMM332

board

• program the CMM332 board

• single-step through a downloaded program in order to verify its correct functionality.

INTRODUCTION

The CMM332 board provided by Axiom is an extension of the Motorola MC68332 BCC

(Business Card Computer) product.

The components of the CMM332 device are the following

• MC68332 Microcontroller Unit (MCU).

• Two 64K x 16 erasable programmable read only memories (EPROMs) that contain

the M68CPU32BUG debugger software

• 32k x 16 bit, byte addressable random access memory (RAM)

The CMM332 can be connected to a Personal Computer via serial port. Any ANSI termi-

nal emulator can be used to communicate with the device. In this lab will we be using the

AxIDE software which is essentially an ANSI terminal emulator.

PRE-LAB:

The following is to be performed prior to attending the scheduled lab session:

• become familiar with the CPU332BUG debugger commands to be used in the Lab by

reading Appendix 2.

• read Lab 1 in its entirety.

Part 1: Setting up serial communication with the board.

Connect the serial cable and the power connector to the CMM332 board. Inspect the

serial cable connector from the PC to the board. Inspect the power connection from the

power bar underneath the desk to the board.
