4 Hardware Setup
4.1 First Connection
The Demonstration Board is connected to a host PC through a USB port. Connection steps
are listed below in the recommended flow order:
1. Install all the required system software as described in the previous section.
2. Make sure the “POWER SEL” jumper is in the “USB” position.
3. Make sure the “VDD” jumper is in the “ENABLE” position.
4. Insert one end of the USB cable into a free USB port of the PC.
5. Insert the other end of the USB cable into the USB connector on the Demonstration
Board. The “POWER” LED will turn on.
6. The first time the Demonstration Board is connected to the PC, Windows recognizes the
instrument and starts the “Found New Hardware Wizard” procedure, asking you to
specify the driver to use for the instrument. On Windows XP (SP2) the following dialog
box will appear.
Select the “No, not this time” option and click the “Next >” button.
7. The following dialog box will appear.
Page 11
Hardware Setup
Click the “Next >” button.
8. Depending on your Windows settings, the following warning may appear.
Note: this warning is related to the fact that the USB driver used by
the Demonstration Board is not digitally signed by Microsoft, and

Click the “Continue Anyway” button.
9. Windows will install the driver files to your system. At the end of the installation, the
following dialog box will appear.
Page 12
Windows considers it to be potentially malfunctioning or dangerous
for the system. However, you can safely ignore the warning, since
every kind of compatibility/security test has been carried out by
SofTec Microsystems.

5 Operating Modes
5.1 Overview
The Demonstration Board can work in two modes: “standalone” mode and “host” mode.
5.2 Standalone Mode
In standalone mode, no PC connection is required. The microcontroller is factory programmed
with a sample application.
To run the built-in example:
Ensure that the “POWER SEL” jumper selects the “UNREG” position.
Ensure that the “VDD” jumper selects the “ENABLE” position.
Ensure that all of the “I/O ENABLE” jumpers are inserted.
Power on the Demonstration Board through the 12 V DC plug-in power supply.
The green “POWER” LED on the board should turn on.
Depending on the temperature sensed by the NTC network, the “LED0”, “LED1” and
“LED2” LEDs will turn on as illustrated below.
Sensed Temperature LEDs
< 10°C
between 10°C and 20°C
between 20°C and 30°C
> 30°C
Press the “SW0” push-button. The “LED0”, “LED1” and “LED2” LEDs will blink.

Operating Modes
5.3 Host Mode
In host mode the program execution is controlled by the host PC through the “USB” connector.
You can use the PC to debug the application by, for example, executing the program step by
step and watching how the microcontroller registers vary, using the provided CodeWarrior
Development Studio.
Note: all MCUs in the RS08 family contain a single-wire background
debug interface which supports in-circuit programming of on-chip non-
i
To work in host mode (using the built-in USB to BDM interface):
Make sure that the two “ENABLE” jumpers in the “USB TO BDM INTERFACE” section
are inserted;
Make sure that the “POWER SEL” jumper is in the “USB” position;
Make sure that the “VDD” jumper selects the “ENABLE” position;
Connect the host PC to the board through the provided USB cable.
volatile memory. This system does not interfere with normal application
resources. It does not use any user memory or locations in the memory
map. The Background Debug Module (also known as Background Debug
Controller, BDC) uses a single-wire communication interface (via the
BKGD line) to allow non-intrusive access to target system memory and
registers.
Please note that the BKGD line is shared with the PTA3 line and the
RESET line is shared with the PTA2 line. The user program, therefore,
must not use the PTA3 line when working in host mode.

6 Application Tutorial
6.1 Overview
This section will provide a step-by-step guide on how to launch your first project and get
started with the CodeWarrior user interface.
6.2 Step-by-Step Tutorial
The sample application is the same as the one described in the “Standalone Mode” section
above, with the exception that the “LED0” LED is not used (since this line is shared with the
BKGD line needed for BDM communication).
1. Set up the board so that it works in host mode (see “Host Mode” above).
2. Ensure that the Demonstration Board is connected to the PC (via the USB cable) and
that the board is powered on.
3. Start CodeWarrior by selecting it in the Windows Start menu.
4. From the CodeWarrior main menu, choose “File > Open” and choose the “\Program
Files\Freescale\CW08 V5.1\(CodeWarrior Examples)\RS08\Evaluation Board
Examples\DEMO9RS08KA2\Asm\Demo\Demo.mcp”.
5. Click “Open”. The Project Window will open.
6. The code of this example is contained in the “main.asm” file. Double click on it to open.
7. From the main menu, choose “Project > Debug”. This will compile the source code,
generate an executable file and download it to the demo board.
8. A new debugger environment will open. From the main menu, choose “Run >
Start/Continue”. The program will be executed in real-time.
9. From the main menu, choose “Run > Halt”. The program execution will stop. The next
instruction to be executed is highlighted in the Source window.
10. From the main menu, choose “Run > Single Step”. The instruction highlighted in the
Source window will be executed, and the program execution will be stopped immediately
after.
11. From the main menu, choose “Run > Start/Continue”. The application will restart from
where it was previously stopped.
Congratulations! You have successfully completed this tutorial! You can continue to
experiment with the CodeWarrior user interface and discover by yourself its potentialities. For
an in-depth guide of all of the user interface features, select “Help > CodeWarrior Help” from
CodeWarrior Development Studio’s main menu.

7 Internal Oscillator Trimming
The MC9RS08KA2 microcontroller features an internal reference clock (32 KHz) which,
through an FLL circuitry, can be used to generate the microcontroller system clock. The
internal reference clock can be calibrated (trimmed) with precision. To do so, open the
Communication Settings dialog box.
To open the Communication Settings dialog box, enter a CodeWarrior debugging session and
select “MCU Configuration” from the “SofTec-RS08” menu. The following dialog box will
appear.
The MC9RS08KA2 microcontroller’s ICSTRM register and the FTRIM bit in the ICSSC register
will be then programmed with a specific value which will result in the DCO output frequency
specified.

9 Troubleshooting
9.1 USB Driver Problems
If you connected the Demonstration Board to the PC before installing the SofTec
Microsystems Additional Components, the Demonstration Board’s USB driver may not have
been correctly installed on your system. Unplugging and replugging the USB cable is of no
use, since Windows has marked the device as “disabled”. As a consequence, the PC cannot
communicate with the Demonstration Board.
To restore the USB driver (provided the SofTec Microsystems Additional Components have
been installed), perform the following steps under Windows XP:
1. Connect the Demonstration Board to the PC.
2. Open the Control Panel (Start > Settings > Control Panel).
3. Open the “System” options.
4. Select the “Hardware” tab.
5. Click the “Device Manager” button.
6. The “uDART In-Circuit Debugger” device will be shown with an exclamation mark next
to it. Double click on this device.
7. In the “General” tab, click the “Reinstall Driver” button. Follow the on-screen
instructions.
9.2 Communication Problems between the PC and the
Demo Board
1. Make sure that the “BKGD” and “RESET” jumpers in the “USB TO BDM INTERFACE”
section are inserted.
2. Make sure that the microcontroller is powered (The “VDD” jumper in the “POWER”
section must select the “ENABLE” position).
3. Make sure that the “POWER SEL” jumper selects the appropriate power source
(typically “USB” when the board is connected to the PC).
4. Make sure that the microcontroller is correctly inserted in its socket.
9.3 “LED0” LED Always Turned On
The “LED0” LED shares the BKGD line (used for the BDM communication). If you want to use
this line as a generic user I/O you must enable this feature in your application software and
remove the “BKGD” jumper in the “USB TO BDM INTERFACE” section of the board. Doing so,
Page 23
DEMO9RS08KA2 User's Manual
however, will make BDM communication between the host PC and the microcontroller
impossible.
