GETTING STARTED  
The Axiom CMD912X single board computer is a fully assembled, fully functional development  
system for the Motorola 68HC912D60/ DG128/ DT128 and MC9S12DP256 microcontrollers,  
complete with wall plug power supply and serial cable. Support software for this development  
board is provided for Windows 95/98 and NT operating systems.  
Follow the steps in this section to get started quickly and verify everything is working correctly.  
Installing the Software  
1. Insert the Axiom 68HC12 support CD in your PC. If the setup program does not start, run  
the file called "SETUP.EXE" on the disk.  
2. Follow the instructions on screen to install the support software onto your PC.  
You should at minimum install the AxIDE for Windows software.  
3. The programming utility “AxIDE” requires you to specify your board. You should select  
"912-xxx" version of your development board.  
Board Startup  
Follow these steps to connect and power on the board for the default Monitor operation. This  
assumes you're using the provided AxIDE utility (installed in the previous section) or a similar  
communications terminal program on your PC. If you're using a different terminal program  
than the one provided, set it's parameters to 9600 baud, N,8,1.  
1. Set the CMD912x board CONFIG SWITCH as follows:

5. Apply power to the board by plugging in the power adapter that came with the system.  
6. If everything is working properly, you should see a message to “PRESS KEY TO START  
MONITOR…” in your terminal window. Press the ENTER key and you should see:  
Axiom MON12 - HC12 Monitor / Debugger  
> _  
7. Your board is now ready to use! If you do not see this message prompt, or if the text is  
garbage, see the TROUBLESHOOTING section at the end of this manual.  
Support Software  
There are many programs and documents on the included HC12 support CD you can use with  
the CMD912X board. You should install what you want from the main menu then browse the  
disk and copy what you like to your hard drive.  
At minimum, you should install the AxIDE program.  
This flash programming utility  
communicates with the board via its COM1 port and the supplied serial cable. This program  
also includes a simple terminal for interfacing with other programs running on the CMD912X  
and information from your own programs that send output to the serial port.  
Also on the disk are free assemblers, the GNU C/C++ compiler tools for HC12, example  
source code, and other useful software. The introductory tutorial in this manual uses the free  
AS12 assembler integrated into the AxIDE program. This is a simple assembler with limited  
capability. For a more powerful assembly tool, install the Motorola MCUez program from the  
CD. This will allow you to used PAGED memory in your application.  
Software Development  
Software development on the CMD912x can be performed using either the Mon12 monitor  
utility installed in EPROM (sockets U6/U7), a third party debugger (NoICE, CodeWarrior, etc.)  
or a Background Debug Module (BDM) connected to the PM12xx Module BDM PORT  
connector. Any of these tools can be used to assist in creating and debugging your program  
stored in RAM (see Memory Map).  
After satisfactory operation running under a debugger, your program can be written to Internal  
Flash Memory by changing the PM12xx Module MODE SWITCH settings and programming it  
using one of the included programming utilities. Your program may l then run automatically  
whenever the board is powered on or RESET is applied.  
Option switches on the board allow for easy transition from operating monitor or debugger and  
user code.

TUTORIAL  
This section was written to help you get started developing software with the CMD912X board.  
Be sure to read the rest of this manual as well as the documentation on the disk if you need  
further information.  
The following sections take you through the complete development cycle of a simple "hello  
world" program, which sends the string "Hello World" to the serial port.  
Creating source code  
You can write source code for the CMD912X board using any language that compiles to  
Motorola 68HC12 instructions. Included on the software disk is a free Assembler.  
You can write your source code using any ASCII text editor. You can use the free EDIT or  
NOTEPAD programs that come with your computer. Once your source code is written and  
saved to a file, you can assemble or compile it to a Motorola S-Record (hex) format. This type  
of output file usually has a .MOT, .HEX or .S19 file extension and is in a format that can be  
read by the programming utilities and programmed into the CMD912X board.  
It's important to understand your development board's use of Memory and Addressing when  
writing source code so you can locate your code at valid addresses. For example, when in  
debug mode, you should put your program CODE in External RAM. In assembly language,  
you locate the code with ORG statements in your source code. Any lines following an ORG  
statement will begin at that ORG location, which is the first number following the word ORG,  
for example: ORG $4400. You must start your DATA (or variables) in a RAM location  
unused by your program, for example: ORG $4000.  
In “debug mode” you’ll be using a debugger utility (Mon12, NoICE, etc) which will handle both  
interrupts (reset, timers, etc) and the STACK. When finished debugging, you must add code  
to your application to handle the STACK and Interrupt vector initialization. Set the stack  
somewhere at the top of your available RAM, for example $3FFE, in assembly this would be  
LDS #$3FFE. Also define the RESET vector address, $FFFE, at the end of your program.  
For example:  
ORG $FFFE  
FDB START ; where START is the beginning label of your program  
A look at the example programs on the disk can make all of this clearer. If you're using a  
compiler instead of an assembler, consult the compiler documentation for methods used to  
locate your code, data and stack.  
5
Assembling source code  
An example program called “HELLO.ASM” is provided under the \EXAMPLES\912x directory  
of the CD and if you installed AxIDE, under that programs \EXAMPLEdirectory. You must use  
the example for the PM Module you have installed on the CMD912x board. The PM Label is  
located beside the microcontroller. For example:  
\EXAMPLE\HC12D60\HELLO.ASM Example program for the PM12D60  
\EXAMPLE\HC12D128\HELLO.ASM Example program for the PM12D128  
\EXAMPLE\HC12D256\HELLO.ASM Example program for the PM12D256  
You can assemble your source code using command line tools under a DOS prompt by typing:  
AS12 HELLO.ASM –LHELLO  
Most compilers and assemblers allow many command line options so using a MAKE utility or  
batch file is recommended if you use this method. Run AS12 without any arguments to see all  
the options, or see the AS12.TXT file on the disk.  
The programming utility AxIDE provided with this board contains a simple interface to this  
assembler. Use it by selecting "Build" from its menu. This will prompt you for the file to be  
assembled. NOTE: You must select your board from the pull down menu first, or it may not  
build correctly.  
DO NOT use long path names (> 8 characters). The free assembler is an old DOS tool that  
does not recognize them.  
If there are no errors in your source code, 2 output files will be created:  
HELLO.S19  
HELLO.LST  
a Motorola S-Record file that can be programmed into memory  
a common listing file which shows the relationship between source  
and output  
The listing file is especially helpful to look at when debugging your program. If your program  
has errors, they will be displayed and no output will be generated, otherwise the listing file will  
be displayed.  
If you prefer a windows integrated programming environment, try the Motorola MCU-EZ tools.  
Refer to the MCU-EZ documentation on the disk for more information.  
Also, a port for the free GNU C compiler and tools for the HC12 is available on the CD under  
\Shareware and also online at www.gnu-m68hc11.org.  
6
Running your application  
After creating a Motorola S-Record file you can "upload" it to the development board for a test  
run. The provided example “HELLO.ASM” was created to run from RAM so you can use the  
Mon12 Monitor to test it without programming it into Flash.  
If you haven’t done so already, verify that the CMD912X board is connected and operating  
properly by following the steps under “GETTING STARTED” until you see the Mon12 prompt,  
then follow these steps to run your program:  
1. Press and release the RESET button on the CMD912X board. You should see the PRESS  
ANY KEY message. Hit the return key ¿ to get the monitor prompt.  
2. Type LOAD ¿  
This will prepare Mon12 to receive a program.  
3. Select Upload and when prompted for a file name select your assembled program file in s-  
record format that was created in the previous section called: HELLO.S19  
Your program will be sent to the board thru the serial port.  
4. When finished loading you will see the > prompt again. Type GO 4400 ¿  
This tells Mon12 to execute the program at address $4400, which is the start of our test  
program.  
5. If everything is working properly you should see the message “Hello World” echoed back  
to your terminal screen. Press RESET to return to the monitor.  
6. If you do not get this message, see the TROUBLESHOOTING section in this manual  
You can modify the hello program to display other strings or do anything you want. The  
procedures for assembling your code, uploading it to the board and executing it remain the  
same. Mon12 has many features such as breakpoints, assembly/disassembly, memory dump  
and modify and program trace. Type HELP at the Mon12 prompt for a listing of commands or  
consult the Mon12 documentation on the disk for more information.  
For a more powerful debugger with many advanced features such as source level debugging,  
you can use the NoICE debugger software. A full featured demo version is provided on the  
CD, which you can use to get started. NOTE: To use this program instead of Mon12 you must  
simply move the CONFIG SWITCH position 3 ON, RESET the board, and run the NoICE  
software. See the help documentation in this program for more information.  
NoICE monitor is not installed on Monitor versions R2 and earlier.  
7
Programming Flash EEPROM  
After debugging, you can program your application into Flash Memory so it executes  
automatically when you apply power to the board as follows:  
1. Make a backup copy of HELLO.ASM then use a text editor to modify it.  
2. Change the ORG location for the program start to the internal flash if needed.  
3. Remove the comment ;character before one of the following lines to initialize the stack  
pointer which is necessary when running outside of a debugger:  
LDS  
LDS  
#$3FFE ; DG/DP128 or DP256 – initialize…  
#$7FE ; D60 - initialize the stack pointer  
4. Remove the comment ;character from before the following 2 lines at the end, to set the  
reset vector to go to the beginning of the program (the label START) when powered on:  
org $fffe  
fdb  
reset vector  
START  
5. Re-Assemble HELLO.ASM as described in the "Assembling Source Code" section.  
6. Select Program from the AxIDE menu and follow the message prompts. When prompted  
for a file name, enter the new HELLO.S19 file.  
7. Press the RESET button on the board before clicking OK. When prompted to Erase,  
choose Yes.  
8. When finished programming, REMOVE POWER then set the MODE SWITCH positions 1  
and 2 OFF. Note: turn position 3 off also for DP256 version.  
9. Re-Apply Power to the board. Your new program should start automatically and the “Hello  
World” prompt should be displayed in the terminal window.  
To return to the Mon12 monitor program, set the MODE SWITCH positions 1 and 2 back ON  
then press RESET. Note: MODE switch 3 also must be ON for DP256 1K79 and earlier mask  
sets.

BDM OPERATION  
The CMD912X board will emulate supported HC12 device internal flash memory in external  
ram. This feature allows BDM (Background Debug Modules) such as the AX-BDM12 to load  
and control the execution of code being developed without the necessity of the internal flash  
memory being programmed many times during the development process. This feature  
improves updating time and allows the use of may software breakpoints instead of being  
limited to only 2 hardware breakpoints.  
Operation Notes for BDM use:  
1)  
CMD912x CONFIG SWITCH should be set 1 ON, 2 OFF, 3 OFF, and 4 ON. Position 5  
should be Off unless the DG/DT128 Fixed Page is desired to be emulated in ram.  
These settings provide external ram and PRU operation with the ECS enabled for  
Paging emulation.  
2)  
PM12xxx MODE SWITCH is usually set for positions 1 and 2 off to select Single Chip  
Mode. This setting forces the BDM Monitor in the HC12 active immediately after Reset  
with the BDM connected which is desired for most BDM pods. The BDM can then load  
a script to set the desired operating mode and configuration, see next note. The  
DP256 version should have Mode Switch position 3 ON for correct operation of the  
MODC select buffer during RESET.  
3)  
The BDM initialization of the HC12 should set the correct operating MODE (Expanded  
Wide for memory access) and enable port emulation for the PRU to operate. The EME,  
EMK, LSTRB, RW, IVIS, ROMEN and Stretch configuration bits should be set for  
proper memory map and PRU operation. The external RAM does not require any cycle  
stretch for accesses up to 25MHz E clock. The Axiom support CD contains sample  
set-up macros for the AX-BDM12.

COM SWITCH  
The 6 position COM SWITCH on the CMD912x Board provides an easy method of connecting  
or isolating the HC12 SCI and CAN channel RXD pins from the provided on-board  
transceivers. The HC12 SCI channels are connected to RS232 transceivers and the first 4  
CAN channels are connected to 1M baud CAN transceivers. To apply the RXD pins on the  
channels for other user applications requires that the transceiver driver be removed from the  
HC12 pin. User may then apply signals to the respective pins at the MCU PORT connector  
without driver conflict. Please note that the on-board monitor(s) require HC12 SCI channel 0  
for user interface.

PORTS AND CONNECTORS  
PRU PORT  
The Port Replacement Unit (PRU) provides simulation of the HC12 bus and control ports A, B,  
E, and K so expanded memory can be used for single-chip application development. PRU  
operation is enabled with external memory by CONFIG Switch 1 ON. The PRU also provides  
control of the external memories and peripherals on the CMD912x board. Care should be  
taken not to violate PRU operation constraints or user code operation could be rendered  
inoperable until a RESET is performed.  
PRU Ports A, B, E, and K are simulated ports due to the different drive characteristics of the  
PRU logic device. Following are the characteristic differences between the HC12 and PRU  
ports:  
1) The PRU will drive ports to TTL levels with 24ma of source current. Greater than the  
HC12.  
2) The PRU provides pull-up resistance of 47K ohms to +5V is applied to all PRU ports. The  
HC12 allows this to be optioned on input ports.  
3) The PRU will only drive outputs high to +4V. The PRU port pull-up resistors raise the  
output level to +5V with minimal drive.  
4) PRU port inputs will indicate logic high if not driven due to the pull-up resistors.  
The PRU will provide HC12 internal resource memory mapping support with constraints. The  
user should be cautious to stay within the bounds of the constraints for proper operation of the  
board. PRU constraints:  
1) The HC12 R/W, LSTRB, and ECLK signals must be enabled for correct operation of the  
PRU.  
2) The HC12 MODE register must have the IVIS, EME, and EMK bits enabled for correct  
PRU operation.  
3) The IVIS bit in the HC12 MODE register must be enabled prior to any HC12 internal  
resource map changes from default locations.  
4) HC12 internal Ram block (INITRM register) cannot be moved above $4000 hex.  
5) HC12 internal Register block (INITRG register) cannot be moved above $8000 hex and is  
treated as a 2K byte memory space.  
6) HC12 internal EEprom block (INITEE register) is treated as a 4K Byte memory space.

CAN1 - 4 PORTS  
These ports provide the CAN Bus input and output. Each port has a CAN Transceiver (Philips  
PCA82C250) capable of up to 1M Baud data rate. Not all HC12 devices support all of the  
channels, refer to the device data for capability. Each transceiver receive output has a COM  
Switch position associated with it. For proper operation the COM Switch should be turned on  
for each CAN channel that is used for CAN communication. The switch provides isolation for  
the HC12 I/O port if the CAN operation is not supported by the device or desired by the user.  
All HC12 I/O ports are available at the Port Headers for other I/O applications.

CAN BUS TRANSMIT ENABLE  
Each CAN port transceiver transmit driver is enabled for maximum drive and minimum slew  
rate by default. The drive and slew rate may be adjusted by changing the value of RC10,  
RC20, RC30, or RC40 for each CAN 1 - 4 port respectfully (see PCA82C250 data sheet for  
more information). These 1206 size SMT resistors are located on the bottom of the CMD912x  
board near the respective CAN port.  
CAN Bus transceiver transmit enable control can be applied to each CAN 1 - 4 Port by the  
RS1 - 4 tie pads respectfully. The user should select an available HC12 I/O port to perform  
the transmit enable function and connect it from the MCU_PORTx pin to RSx pad as required.  
The RC10, RC20, RC30, or RC40 resistors must be removed from the respective CAN  
port to apply transmit enable control. The transmit enable signal to the CAN transceivers is  
active logic low.  
CAN BUS TERMINATION  
Each CAN port has a set of 1206 SMT size termination resistors on the bottom of the  
CMD912x board that are not installed at the factory. The termination resistors provide  
optional bias and termination impedance for the CAN bus connected to the CAN 1 - 4 ports.  
Type of wire media, data rate, length of wire, and number of CAN bus nodes can all effect the  
requirement or value of the termination for the CAN bus. User should refer to particular  
application for termination requirements.  
CAN-H Bias Resistors: RC11, RC21, RC31, and RC41 provide bias to ground potential for  
CAN 1- 4 ports respectfully.  
CAN-L Bias Resistors: RC13, RC23, RC33, and RC43 provide bias to +5V potential for CAN  
1- 4 ports respectfully.  
CAN Termination Resistors: RC12, RC22, RC32, and RC42 provide termination between  
CAN-H and CAN-L signals for CAN 1- 4 ports respectfully.

LCD_PORT  
The LCD_PORT interface is connected to the data bus and memory mapped into the Register  
Following memory area of the HC12. Note that the DP256 does not support the LCD Port due  
to no Register following area is available. Refer to the PM12xxx board memory map for LCd  
Port address location. For the standard display, the base address of the LCD Port is the  
Command register and the Base+1 address is the display Data register.  
The interface supports all OPTREXä DMC series displays in 8 bit bus mode with up to 80  
characters and provides the most common pinout for a dual row rear mounted display  
connector. Power, ground, and Vee are also available at this connector.

TB1 and J6 Power  
The TB1 and J6 connectors provide power input to the board or if J6 is used for input, TB1  
maybe used to source additional circuitry. The J6 power jack accepts a standard 2.0 ~ 2.1mm  
center barrel plug connector (positive voltage center) to provide the +VIN supply of +7 to +20  
VDC @ 300ma minimum (+9VDC nominal). TB1 provides access to the +VIN, GND (power  
ground), and +5V power supplies. The CMD912x power supply will provide 500ma of +5V for  
user application. +VIN input power should only be applied by J6 or TB1, not both or a supply  
conflict may occur and the CMD912x board could be damaged.  
BDM PORT  
The BDM port on the PM12xxx module is a 6 pin header compatible with the Motorola  
Background Debug Mode (BDM) Pod. This allows the connection of a background debugger  
for software development, programming and debugging in real-time without using HC12 I/O  
resources.

TROUBLESHOOTING  
The CMD912X board is fully tested and operational before shipping. If it fails to function  
properly, inspect the board for obvious physical damage first. Ensure that all IC devices in  
sockets are properly seated. Verify the communications setup as described under GETTING  
STARTED and see the Tips and Suggestions sections following for more information.  
The most common problems are improperly configured communications parameters, and  
attempting to use the wrong COM port.  
1. Verify that your communications port is working by substituting a known good serial  
device or by doing a loop back diagnostic.  
2. Verify the MODE, CONFIG, and COM switch settings are correct.  
3. Verify the power source. You should measure approximately 9 volts between the GND  
and +VIN connections on the TB1 power connector with the standard power supply  
provided.  
4. If no voltage is found, verify the wall plug connections to 115VAC outlet and the power  
connector.  
5. Verify the logic power source. You should measure +5 volts between the GND and +5V  
connections on the TB1 power connector. If the +VIN supply is good and this supply is  
not +5V, immediately disconnect power from the board. Contact [email protected] by  
email for instructions and provide board name and problem.  
6. Disconnect all external connections to the board except for COM1 to the PC and the wall  
plug.  
7. Make sure that the RESET line is not being held low.  
Check for this by measuring the RESET pin on P4 for +5V.  
8. Verify the presence of a 16MHz square wave at the EXTAL pin or 8MHz E clock signal if  
possible.  
9. Contact [email protected] by email for further assistance. Provide board name and  
describe problem.

Tips and Suggestions  
Following are a number of tips, suggestions and answers to common questions that will solve  
many problems users have with the CMD912X development system. You can download the  
latest software from the Support section of our web page at:  
Utilities  
·
·
·
If you’re trying to program memory or start the utilities, make sure all jumpers and  
CONFIG SWITCH settings are correct.  
Be certain that the data cable you’re using is bi-directional and is connected securely to  
both the PC and the board. Also, make sure you are using the correct serial port.  
Make sure the correct power is supplied to the board. You should only use a 9 volt,  
300 mA adapter or power supply. If you’re using a power strip, make sure it is turned  
on.  
·
Make sure you load your code to an address space that actually exists. See the  
Memory Map if you’re not sure. The CONFIG switch changes the memory map.  
·
·
If debugging under Mon12, make sure you're not over-writing RAM used by it.  
If you’re running in a multi-tasking environment (such as Windows™) close all  
programs in the background to be certain no serial conflict occurs.  
Code Execution  
·
·
Make sure the CONFIG SWITCH is set for the proper mode.  
CONFIG switch 3 must be ON to access the external bus (LCD display, etc) even if  
executing code from Internal Flash memory.  
·
·
·
·
Under Mon12, breakpoints may not be acknowledged if you use the CALL command.  
You should use one of the GO command instead.  
Check the HC12 reset vector located at FFFE - FFFF. These 2 bytes contain the  
address where execution will begin when the unit is powered on.  
When running your code stand-alone, you must initialize ALL peripherals used by the  
micro, including the Stack, Serial Port, Reset and Interrupt vectors etc.  
You must either reset the COP watchdog timer in the main loop of your code or disable  
it when not running under Mon12 or BDM mode. The micro enables this by default and  
if you don't handle it your code will reset every couple of ms.

TABLE 1. LCD Command Codes  
Command codes are used for LCD setup and control of character and cursor position. All  
command codes are written to LCD panel address $B5F0. The BUSY flag (bit 7) should be  
tested before any command updates to verify that any previous command is completed. A  
read of the command address $B5F0 will return the BUSY flag status and the current display  
character location address.
