Hi
I have an example circuit built on a 12F675 that calls for an external 4K crystal. In a nutshell, I was wondering... "why?" [the crystal that is). I understand these chips to have an internal oscillator that can be enabled with the proper configuration word, in which case why would someone use an external crystal as a clock? Can someone explain it or point me at some explanation?
Thanks
