Can anyone please tell me whether there are any restrictions on the = state of pins other than those used during the programming cycle? I.e., Apart from _MCLR, RB6, RB7 (and obviously power supply and ground) = does it matter whether I connect any positive voltage or ground to any = other pin while I'm programming a PIC? Some simple programming circuits = leave them floating, but to simplify in-circuit programming, I would = like to leave some pins connected.
