I am assuming that when you use DEVICE PROTECT option, it is applied when you do a RUN, PROGRAM, and DEBUG. So, you have to be aware of the fact that you are using that option, other wise it could create some havoc. Also, is their code overhead that you have to be concerned about. When the scrambling is done and the chip is programmed, the chip has to know how to work with the code, correct. I guess what I am after is, if you write a program that is going to use the max code space, and you know you will be using the protect option, how much code space should be left available, or am I on the wrong path with this.
