I have a project to convert code from a M68HC08 to a newer processor. I have converted the code to a MC9S08SH8 using Code Warrior and a DEMO9S08SH32 Demo board. The first part of the program is most delays to allow some of the devices to be initialized. If I run the code from the start with a break point where I want to stop in the program, the output on the debugging laptop displays frequency changing ~15Mhz and the program seems to stop running. If I run the code and put breakpoint in to make the code execute in smaller quantities the program works without any problems. If I stop the program after it has stopped running the frequency reverts back to the ~8.0Mhz like it should be. No sure what is causing this to happen, maybe a software/hardware interrupt or just something between the CPU and the debugging system. If you can give me any information as to where to look please replay.
Added p/n to subject.
