Microchip have written an application note that you can look into.
AN606 Low Power Design Using PIC16/17
http://www.microchip.com/1010/suppdoc/appnote/category/listing/index5.htm=
#93

It says:

=95 All unused I/O pins should be configured as
outputs and set high or low. This ensures that
switching currents will not occur due to a floating
input.

=C4mne: [PIC]:What is the correct way to terminate unused pins 16F877

I will have several unused pins on my 16F877

Should the unused pins be set as inputs or outputs and should they be tie=
d
directly to GND or do I use a resistor.
