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 DEMO908GZ60 module:
a) This product as shipped from the factory with associated power supplies and cables, has
been verified to meet with requirements 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 other
apparatus in the immediate vicinity. If such interference is detected, suitable mitigating
measures should be taken.
TERMINOLOGY
This development module uses option selection jumpers. A jumper is a plastic shunt that con-
nects 2 terminals electrically. Terminology for application of the option jumpers is as follows:
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.
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 in-
stall a suitably sized 0-ohm resistor or attach a wire across the pads.

FEATURES
The DEMO908GZ60 is an evaluation or demonstration module for the 68HC908GZ60
microcontroller. Development of applications is quick and easy with the included wall plug,
DB9 serial cable, sample software tools, and examples. The MON08 port is provided for
development tool application and is compatible with HC08 monitor interface cables and
software. The module provides options to allow MON08 access through the COM port also. A
40-pin MCU I/O connector (J1) allows interfacing the DEMO908GZ60 module to external
connections.
