GETTING STARTED
Thank you for purchasing our CME12B32 development board! The Axiom CME12B32 single board computer is a fully
assembled, fully functional development system for the Motorola 68HC12B32 Microcontroller, complete with wall plug
style power supply and serial cable. To get started quickly, perform the following test now to make sure everything is
working correctly:
1. Create a directory on your PC hard drive for the utility software and copy the contents of the UTL-12B32 disk to that
2. Connect one end of the supplied 9-pin serial cable to a available COM port on your PC. Connect the other end of the
3. Apply power to the board by plugging in the power supply that came with the system.
4. Change to the directory containing the utility software and execute the program: AX12.EXE.
5. Select the PC COM Port that you’re using to attach the development board.
6. Select the development board type: CME12-B32.
7. From the main menu select “Terminal Window”.
8. Press then release the RESET button on the CME12B32 board now.
9. If everything is working properly, you should see the monitor prompt in the terminal window. Your board is now ready
If you do not see the monitor/debugger message prompt, or the text is garbage, see the TROUBLESHOOTING section of
this manual.
DEVELOPMENT PHILOSOPHY
Software development on the CME12B32 can be performed using either the DBUG12 monitor utility installed in EPROM
(sockets U6/U7), the DBUG12 monitor programmed into the internal Flash EPROM or a Background Debug Module
(BDM) connected to the DEBUG connector. Any of these tools can be used to assist in creating and debugging your
program that is stored in either internal RAM ($800-$C00) or external RAM (U4/U5 see Memory Map).
After satisfactory operation running under a debugger, your program can be written to the Internal Flash Memory by
relocating its start address to $8000 and programming it using either the included AX12 program or a BDM. Your program
will then run automatically whenever the CME12B32 is powered on or RESET is applied.
Option jumpers on the board allow for easy transition from one memory type to another and restoring an operating
monitor.
