So I'm venturing away from the PIC16F168A and it's internal oscillator for the first time ever. I need to drive an old BIT display with +5v and -5v. I bought the PIC16F57 because it has enough I/Os to do the job. So I go into the data sheet and after reading it over and over (8 hours worth!), I'm thoroughly confused about the resonator setup. I bought some Murata CSTLS20M0X53-B0 20 MHZ resonators, but now I'm not sure if I can use them. If I can use them, how is the resonator connected to the IC correctly?

Now for the code ... if I could get an example of a simple code to toggle a port from low to high a few times a second, I can figure out the rest. Any help at all is greatly appreciated!
