And on a 16F689 running on internal oscillator, for I/O on both OSC1 & 
OSC2 pins, be sure to set the config word to INTOSCIO and not INTOSC. 
Otherwise you could spend half a day trying to find out why only one of 
the two pins behaves as an I/O.

It would have been better if they had called it INTOSCCLK instead of INTOSC.

Anyway...
