As somebody already mentioned, the main part of the answer is to set the
pins as inputs - in other words, write 0xFF to all the TRIS registers.
An additional trick to minimize power consumption is to make sure that
the weak pullups on PORTB are turned off. Finally, you should also turn
off the A/D converter.
