CAUTIONARY NOTES
1) Electrostatic Discharge (ESD) prevention measures should be used when handling this
product. ESD damage is not a warranty repair item.
2) Axiom Manufacturing does not assume any liability arising out of the application or use of
any product or circuit described herein; neither does it convey any license under patent
rights or the rights of others.
3) EMC Information on the DEMO9S12XDT512 board:
a) This product as shipped from the factory with associated power supplies and cables,
has been verified to meet with requirements of CE and the FCC as a CLASS A product.
b) This product is designed and intended for use as a development platform for hardware
or software in an educational or professional laboratory.
c) In a domestic environment, this product may cause radio interference in which case the
user may be required to take adequate prevention measures.
d) Attaching additional wiring to this product or modifying the products operation from the
factory default as shipped may effect its performance and cause interference with
nearby electronic equipment. If such interference is detected, suitable mitigating measures should be taken.
TERMINOLOGY
This development module utilizes option select jumpers to configure default board operation.
Terminology for application of the option jumpers is as follows:
Jumper – a plastic shunt that connects 2 terminals electrically
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 jumpers
be idled by installing on 1 pin so they will not be lost.
Cut-Trace – a circuit trace connection between component pads. The circuit trace may be
cut using a knife to break the default connection. To reconnect the circuit, simply install a
suitably sized 0-ohm resistor or attach a wire across the pads.
Signal names followed by an asterisk (*) denote active-low signals.

GETTING STARTED
To get started quickly, please refer to the DEMO9S12XDT512 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
correct version of CodeWarrior Development Studio, and load an Analog to Digital (ATD) test
program using CodeWarrior.
OPERATING MODES
The DEMO9S12XDT512 board operates in two operating modes: Run Mode, or Debug Mode.
Run Mode allows user application operation from Power-On or Reset. Debug Mode supports
the development and debug of applications. 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
