Support Software
There are many useful programs and documents on the included HC12 support disk that can
make developing projects on the CME-12B/BC easier. You should browse the disk and copy
anything you want to your hard drive. See the README.TXT file for a description of what is
included.
The flash programming utilities communicate with the board via its COM1 port and the
supplied cable. These programs also include a simple Terminal for interfacing with other
programs running on the CME-12B/BC, such as the D-Bug12 and information from your own
programs that send output to the serial port.
Also on the disk is a free assembler, example source code, and other tools to get you started.
Software Development
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 BDM-IN connector.
Any of these tools can be used to assist in creating and debugging your program 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 programming utilities or a BDM. Your program will then run automatically
whenever the board is powered on or RESET is applied.
Option jumpers and switches on the board allow for easy transition from one memory type to
another and restoring an operating monitor.
