TERMINOLOGY

This development board uses option selection jumpers. A jumper is a plastic shunt that con-

nects 2 terminals electrically. Terminology for application of the option jumpers is as follows:

Jumper on, in, or installed - jumper is installed such that 2 pins are connected together.

Jumper off, out, or idle - jumper is installed on 1 pin only. It is recommended that jump-

ers be idled by installing on 1 pin so they will not be lost.

GETTING STARTED

To get started quickly, please refer to the DEMO908QB8 Quick Start Guide. This quick start

will show the user how to connect the board to the PC, run a LED test program, install the cor-

rect version of CodeWarrior Development Studio, and load an Analog to Digital (ATD) test pro-

gram using CodeWarrior.

OPERATING MODES

The DEMO908QB8 board operates in two basic modes Run Mode, or MON08 Debug Mode.

Run Mode supports user application operation from Power-On or Reset. MON08 Debug Mode

supports the development and debug of applications via the MON08 embedded debug

monitor. See the related sections below for quickly starting the board in the desired operation

mode.

The board has been preloaded with a demonstration program. The demo program operates in

the Run Mode. The +5V LED will light when power is applied to the board.

RUN Mode

Run mode allows user application to function when power is applied to the board. Use the

following settings to configure the DEMO908QB8 board for RUN Mode to get started quickly.

1. Connect a serial communication cable (not inlcuded) between the board and a host PC if

needed for the application. Launch supporting host communication software as needed.

2. Connect auxiliary equipment to board as required by application.

3. Configure the board option jumpers for run mode.
