I'm assuming the rated pin current >capacity determined the whole current consumption of the PIC? Yes, you must really be running in a low-current situation. OTOH, you COULD use this to de-polarize your system. If you READ the ports, see which is high and which is low, you could then use it to power the system if somehow the pins were connected to the "wrong" power rails. Heh, just because it works doesn't mean it's recommended!
