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 jump-
ers be idled by installing on 1 pin so they will not be lost.

FEATURES
The DEMO9S12XDT512 is an evaluation or demonstration board for the Freescale
MC9S12XDT512 MCU. Development of applications is quick and easy with the integrated
USB-Multilink BDM, sample software tools, and examples. A standard BDM debug port is also
provided, but not populated, to allow use of an external BDM pod. Two 40-pin connectors al-
low the demonstration board to be connected to an expanded evaluation environment or to
external test equipment.
