Check for samples.  Microchip wants you to experiment.  (That site would 
likely give lynx fits, though; it even gave my graphical browser fits).

I looked at the datasheet for that chip.  What's interesting is the high 
voltage tolerant port, so you can have an arbitrary supply voltage like 
7.2v, and then port B's I/O would operate in a 7.2 volt environment, 
too.  And it would tolerate a drifting battery voltage, from a digital 
standpoint, assuming you are aware of the implications.
