Hi guys , i m working on pic18f2580 using 8 mhz crystal oscillator with 22 Pf capacitor, but my some programs are not working , now looking over the data sheet in oscillator configuration topic , it says
so i want to ask for which oscillator it is required is it for crystal oscillator , i m also posting my schematics for pic18f2580 system . also please verify my settings.If HS is
selected, it is possible that the gain of the
oscillator will overdrive the resonator.
Therefore, a series resistor should be
placed between the OSC2 pin and the
resonator. As a good starting point, the
recommended value of RS is 330Ω.
