DEMO9S08SE8 Lab
This lab document applies to
DEMO9S08SE8.
Start each lab with the board powered
ON. Make sure to use only one utility at a
time, as they share the same USB source.

Setting up the Demo
1. Connect the DEMO9S08SE8 demo board to the PC
2. Open both the CodeWarrior IDE and the SE8_DEMO_
3. To compile the project and program the MCU, select “P&E
5. After the MCU is programmed, start the TerminalWindow.

This document explains how to set up and use the SE8_DEMO_LAB1 example application. The example application allows
the user to try out several features on Freescale’s MC9S08SE8 microcontroller.

application is:
• SW1, SW2, LED1, LED2, RV1, RZ1 jumpers are installed
• COM_SEL switches to BDM

debugger application and prompt the user with “Erase
and program FLASH.” Click “Yes.” The MCU is now

exe from the DEMO9S08SE8 Toolkit directory. It will open
a terminal window connected to USB port. The USB COM
port settings must be:
• 38400 baud rate
• 8 bits
• No parity
• 1 stop bit
The demo is now ready to run.

Running the Demo
Now click the “RUN” button. If everything is configured
correctly, LED1 and LED2 will begin to blink alternately and
the terminal window will display the following as soon as the
demo starts:

This demo relies on the internal clock reference to
generate bus frequency and the communications baud
rate. Therefore, the MCU’s internal clock reference has
been trimmed to 32 kHz.
After every chip reset, the terminal will display the
system reset status and state the cause or causes of the
last reset.
MC9S08SE8 is configured as an IRQ pin function. The
user can use the IRQ function to wake the MCU from low-
power mode.

RV1 jumper.
intensity of the light shining on the RZ1 sensor changes,
the RZ1 jumper voltage will vary from 0V to 5V—the
lower the light, the higher the voltage. Usually, in a room
environment, the RZ1 jumper voltage is about 5V, so the
user needs a light source, such as lamp, to drive lower
RZ1 jumper voltages.

Demo Menu Options
The user can choose from three options to explore a few of
the MC9S08SE8’s features and go to the submenu of each
function.
To make a selection, simply type the number next to the
menu item.
[1] Real-time clock setup
Real-time clock menu:
Please select a number to execute.
These menu options let the user enable, disable and exit the
real-time clock, which is the basis of the RTC module.
When number 1 is selected, the clock is enabled and
displayed on the terminal after the current time input. Please
enter the current time according to the display: format as
HHMM (H=hour, M=minute). The clock will be displayed on
the terminal.
When number 2 is selected, the RTC is disabled, and the
clock disappears from the terminal.
[2] TPM1 PWM setup
Please select test number to execute.
These options let the user enable or disable the PWM
function of TPM1.
When number 1 is selected, LED1 connected to TPM channel
0 and LED2 connected to TPM channel 1 begin to blink
alternatively. When number 2 is selected, LED1 and LED2
stop blinking.
Step
[1]: Set up, enable and display real-time clock
[2]: Disable real-time clock
[e]: Exit real-time clock menu
TPM1 menu:
[1]: Enable TPM1
[2]: Disable TPM1
[e]: Exit TPM1 menu

[3] ADC menu
Please select test number to execute.
When number 1 is selected, the analog-to-digital converter
(ADC) is enabled to sample the output of RZ1. LED2
illuminates if the voltage on the photo sensor (RZ1) is higher
than 4V. If the RZ1 voltage is less than 4V, LED2 will not light
up. When number 2 is selected, the ADC is turned off.
[1]: Enable ADC to measure the RZ1
[2]: Disable ADC
