Hello all,

I was using a 20Mhz ceramic osc (with built in caps) wit all my PIC16F876's, I'm switching to PIC18F252, can I use the same osc? how do I configure the fuses with this osc?

Thank you in advance

I particulary use 20MHz Xtal with the PIC18F252 but It's ok to use the resonator.

I've used a 4mhz resonator and a 20mhz xtal on the 18fx42 chips, and used #fuses HS,... on both.

Use XT for 4MHz
Use HS for 20MHz
