1 INTRODUCTION
1.1 Overview
The DEMO9S08QB8 is a low-cost development system designed for
demonstrating, evaluating, and debugging the Freescale MC9S08QB8
microcontroller. P&E’s Embedded Multilink circuitry on the DEMO9S08QB8
board allows the processor on the DEMO9S08QB8 to be debugged and
programmed via USB from the PC. In addition, the demo board can be
powered using the USB bus.
Note: Freescale has an older device called 908QB8. 908QB8 is different from this
new 9S
sure that the resources pertain to the 9S
device.

electrostatic discharge.
2 HARDWARE FEATURES
The DEMO9S08QB8 is a demonstration and development system for
Freescale’s MC9S08QB8 microcontroller. Application development is quick
and easy using P&E’s Embedded Multilink circuitry and the included software
tools and examples. An optional BDM port is provided to allow use of an
external BDM interface such as P&E’s Cyclone PRO automated programmer
or USB Multilink. The USB Multilink is functionally comparable to the
DEMO9S08QB8’s Embedded Multilink circuitry.
Note: The DEMO board’s onboard Embedded Multilink circuitry is intended to
function with the onboard processor and any daughter cards that may be
included. It cannot be used to communicate with other devices.

2.2 On-Board Logic Analyzer
The DEMOQE board has a built-in 2-channel logic analyzer which may be
used to display captured data in real-time on a host PC. The logic analyzer
channels (IN0/IN1) are connected to the PTC0 and PTC1 signals on the
DEMOQE board by default via the J11 jumpers. The channels may be
connected to any of the processor pins by wire jumpers (not included).
The DEMOQE Logic Analyzer Utility, included in the DEMOQE Toolkit on the
accompanying DVD-ROM, displays the logic analyzer signals on a PC.
4 DEMO9S08QB8 User Manual
2.3 On-Board Virtual Serial Port
The DEMOQE board has a built-in virtual serial port which may be connected
to the QE processor’s SCI RXD/TXD. This allows certain PC applications to
be able to connect in a serial fashion to the microcontroller without the actual
use of serial port hardware.
The DEMOQE Terminal Window Utility, included in the DEMOQE Toolkit on
the accompanying DVD-ROM, is a generic serial port utility which works with
the DEMOQE virtual serial port or actual serial port hardware.
2.4 DEMOQE Daughter Card Features
• Four bottom-mounted asymmetrically positioned 8x2 female
connectors to mate with the DEMOQE Base Board
• A top-mounted MC9S08QB8CWL chip
2.5 DC9S08QB8 Specific Connections
The labels on the DEMOQE do not necessarily represent actual pin port
function from the MC9S08QB8 microcontroller. In order to take full advantage
of the DEMOQE Base Board resources, MC9S08QB8 signals are mapped to
the DEMOQE Base Board 64-Pin Header as following:

3.3 Software Setup
3.3.1 Installing CodeWarrior Development Studio
To install the CodeWarrior Development Studio, insert the CodeWarrior CD
into your computer’s DVD-ROM drive. A start-up window will automatically
appear. Select CodeWarrior Installation and follow the on-screen instructions.
8 DEMO9S08QB8 User Manual
Note: After installation of CodeWarrior 6.2, it is also required that you install the
S08QB8 service pack.
3.3.2 Installing P&E Resources
Use the DEMOQE Resources DVD-ROM to access and install P&E resources
for the DEMO9S08QB8. These materials are not required for operation. The
support materials contained on the DEMOQE Resources DVD-ROM are
listed in Section 1.4 - Recommended Materials On DEMO9S08QB8
Resources CD.
3.4 Quick Startup
Only a few steps are required to get the DEMO9S08QB8 up and running:
Step 1. Make sure that both CodeWarrior Development Studio v.6.2 and
the S08QB8 service pack are installed on your PC. Additional
information regarding CodeWarrior can be found at
www.freescale.com.
Step 2. Remove the DEMO9S08QB8 demonstration board from its anti-
static pouch. The green MC9S08QB8 daughter card should be
plugged into the header on the base board.
Step 3. Connect the USB cable from your computer to the
DEMO9S08QB8 demonstration board. Depending on your
operating system, you may need to follow steps to install the USB
driver from the DEMOQE Resources DVD-ROM. Once the USB
cable is connected properly the green USB LED on the
DEMO9S08QB8 should illuminate.
Step 4. Turn on the DEMO9S08QB8 power switch (K6). The red Power
LED should illuminate.
Step 5. First press the button labeled “PTA2.” The buzzer will sound and
PTC0 will output a fixed 75% duty cycle pulse width modulation
(PWM) signal. LEDs PTC0 to PTC2 remain on.
Press the PTA2 button a second time. the buzzer will sound again
and the PTC0 PWM duty cycle will change to 25%. LEDs PTC0,
PTC1,and PTC3 are illuminated.
Press the PTA2 button a third time, and then rotate the
potentiometer. The light intensity of LED PTC0 and the tone of the
DEMO9S08QB8 User Manual 9
buzzer will vary as you rotate.
Pressing the PTA2 button a fourth time or pressing the PTA3
button at any time will turn off the buzzer sound and all the LEDs.
Step 6. Optionally, you may run the DEMOQE Logic Analyzer Application
available in the DEMOQE toolkit on the CD. This PC-based
application graphs the IN0 and IN1 signals on the DEMOQE
board. If both J11 jumpers are installed, IN0 shows PTC0 and IN1
shows PTC1. Push button PTA2 three times after reset and turn
the potentiometer to change these signals. This application may
also be found at:
http://www.pemicro.com/fixedlinks/demoQEtoolkit.html.

3.5 Hardware Setup
3.5.1 First-Time Connection
The DEMO9S08QB8 may be connected to a PC through a USB port.
Connection steps are listed below in typical order:
1. Install the required software, as described in the previous section.
2. Make sure the jumpers for USB_PWR, 3V for VOLT_EN, and
REG_VDD for VDD_SELECT are installed.
3. Plug the USB cable A-M connector into a free USB port of the PC.
