1 Introduction
This guide provides the steps necessary to begin
development with a HCS12 family
microcontroller (MCU) using your application
module and/or in conjunction with the Freescale
project board (PBMCUSLK).
This guide is separated into three main sections.
First, the software setup section will assist in
installing the CodeWarrior™ development
tools. Second, the hardware setup section will
step through configuring the project board and
application module. Third, the development
section illustrates how to create, build, and
debug an application.
Refer to the project board user guide,
application module user guide, and
CodeWarrior documentation for more details.

2 Unpack
Open the shipping carton and remove the contents. Locate the packaging list and verify items have been
received from the packaging list.
Inspect both the project board and the application module for damage that may have occurred during
shipping. If damage is found, contact www.freescale.com/support for assistance.
3 Software Setup
The following software installation is a one-time, required procedure per host PC that you intend to use
with the project board and/or application module. After completing the software setup on your host PC,
you can skip the software section on subsequent uses of your project board and/or application module
and begin the hardware setup or development sections.
To install and register CodeWarrior development tools for HCS12(X) Microcontrollers onto a host PC,
complete the instructions found inside the CodeWarrior Development Studio for Freescale HCS12(X)
Microcontrollers case.
Additional tools and training materials for CodeWarrior are available at www.freescale.com
NOTE
Academic Edition development tools are full-featured and not for commercial development. They may
only be licensed to students, faculty, and staff of accredited institutions.
Periodically check http://www.freescale.com/codewarrior for updates and patches to your development
tools. For questions on CodeWarrior development tools, visit http://www.freescale.com/support
4 Hardware Setup
For more information on the Application Module operation, jumper descriptions and settings please
refer to the development board User Guide or visit www.freescale.com\universityprograms for latest
information.

4.1 Configuring the Application Module for independent operation
1) By default, the application module is configured to run independently out of the box. Verify that
all the jumper settings are configured properly on the application module as shown by Figure 1.
2) Plug in the USB cable from the host PC (running CodeWarrior) to the Application Module.
3) Your Done! Proceed to Running your Demonstration application.

4.2.2 Configure the Project Board
Place the project board on a flat and sturdy surface. Ensure sufficient space is available around the
project board to safely construct and test prototyped circuits.
Verify that all the jumper settings are configured properly on the project board as shown by Figure 3.
Highlighted blocks indicate the on or installed position of jumpers. Circles indicate the location on the
project board where the jumpers are located.
