Xiaofan,

Thanks for the feedback.

Yes I have the source code and the target hardware and a ICD2. I could step through the code to see the operation - I have been trying to do this but I felt that I would understand it better if there was some way of documenting the code. This would just give me that helping hand to get a better feel for the overall control.

The code is not huge there is about 1000 lines of assembler.

Thanks,
John
