1) pic12F629 has the capacity to be run at 20 Mhz - does that include using the internal oscillator? For example, if I put DEFINE OSC 20 at the top of my code (After @ DEVICE pic12f629, INT_OSC), will it run at 20 Mhz?

2) Can I use one external oscillator for two PICs, or should they each have their own?
