That line is from the template-file from Microchip's MPLAB-tutorial, I
have no idea what the values are so I left them untouched. It seems
it's possible to change them from the menu in case I need it (which I
obviously seem to do).

But again, this is my first glance with PICs so I don't yet know all
this kind of black magic (the datasheet is pretty heavyweight and I
haven't got through it all). It does, however - according to what you
write, look like I've run into a problem since I need a
32.768kHz-crystal.

I guess I'll have to trim down the inputs to three and multiplex them
together using diodes. Ugh.
