Hi all,

I'm a beginner in electronics and this may very well be a stupid question. I'm u
sing the 16F84 chip and In most circuits that I've seen, there are two capacitor
s connected to OSC1 and OSC2 (33pF). But I have tried connecting the xtal withou
t these capacitors and the controller still seems to work. My question is, what
is the reason for these two capacitors?

Thank you
