Cautionary Notes
1) Electrostatic Discharge (ESD) prevention measures should be applied whenever 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 M68EVB912C32 board:
a) This product as shipped from the factory with associated power supplies and cables, has
been tested to meet with requirements of CE and the FCC as a
CLASS A
product.
Freescale Semiconductor, Inc...
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 also cause interference with
other apparatus in the immediate vicinity. If such interference is detected, suitable
mitigating measures should be taken.
Terminology
This development board applies option selection jumpers. Terminology for application of the
option jumpers is as follows:
Jumper on, in, or installed = jumper is a plastic shunt that fits across 2 pins and the
shunt is installed so that the 2 pins are connected with the shunt.
Jumper off, out, or idle = jumper or shunt is installed so that only 1 pin holds the shunt,
no 2 pins are connected, or jumper is removed. It is recommended that the jumpers be
idled by installing on 1 pin so they will not be lost.
This development board applies hardwired option selections for several option jumper
selections. This option selection applies a circuit trace between the option pads to complete a
default connection. This type connection places an equivalent Jumper Installed type option.
The circuit trace between the option pads may be cut with a razor blade or similar type knife to
isolate the default connection provided. Applying the default connection again can be
performed by installing the option post pins and shunt jumper, or by applying a wire between
the option pads.

GETTING STARTED
The M68EVB912C32 single board computer is a fully assembled, fully functional development
board for the Motorola MC9S12C32 microcontroller. Provided with wall plug power supply,
support disk, and serial cable. Support software for this development board is provided for
Windows 95/98/NT/2000/XP operating systems.
Development board users should also be familiar with the hardware and software operation of
the target HCS12 device, refer to the provided Motorola User Manual for the device and the
HCS12 Reference Manual for details. The EVB board purpose is to promote the features of
the 9S12C32 device or to assist the user in quickly developing an application with a known
working environment. Users should be familiar with memory mapping, memory types, and
embedded software design for the quickest successful application development.
Application development may be performed by applying the provided embedded serial
interface
Debug Monitor,
or by applying a compatible HCS12 BDM cable with supporting host
software. The debug monitor dedicates the SCI serial port as its connection to the host PC and
does not use the traditional background debug mode, thus eliminating the necessity for a
background debug mode cable.
The
Debug Monitor
in conjunction with a program running on a host personal computer (PC)
provides an effective and low cost debug method. Debug monitor operation enables a user to
erase device FLASH memory, program FLASH memory, load application programs, and
debug the application programs. Free host software is available for execution on a PC as an
interface to the monitor.
Debug monitor firmware is provided in the development board HC12 device internal flash
memory and applies some HC12 resources for operation. See the Monitor commands
application note from Motorola for details and the Debug Monitor chapter in this manual for
more information. User applications operated under monitor control may be configured for
dedicated operation by applying the User Reset Vector (0xF7FE/F) and programming the
application into the device flash. The monitor will remain in protected flash memory for future
use if needed.

M68EVB912C32 STARTUP
1) Apply power to the EVB board with the provided wall-plug power supply.
2) Install the provided serial cable between the EVB board COM1 port and an available COM
port on the host PC.
3) Install monitor hosting software on the host PC and launch.
4) Set the EVB board ON - OFF switch to the ON position and verify the POWER indicator is
ON. The EVB is ready to use.
5) Note that if the User Reset vector is programmed, the SW1_EN option jumper must be
installed and SW1 position 6 set to the ON position to enable the monitor.
