For one of my projects I am interested to see how someone else implemented their concept. I wanted to tap onto their microprocessor and read that code. First question I have, if I am to solder wires to the pins of the microprocessor, to which ones should I solder in order to be able to read anything back? Also, I read about lock bits, for my own future security, if I leave the lock bits off, is there a method to trigger lock bits on if someone does any hardware changes (as in trying to tap to the microcontroller)?
