Howdy, Does anyone have a pointer to a more thorough explanation of the PIC (in my case 18F1320 and 18F452) code protection options than the data sheet provides? It's not clear to me after reading the very terse explanation exactly how this works. For example, I'm not sure what the point of the code protection bits is if you can read code with the table read instructions (as seems to be suggested by the data sheet). Any info much appreciated!
