I appologise if this question is over asked but i have searched high and low to no avail so far.
I am using the PIC18F458 and would like to know:
1. The internal oscillator frequency?
2. Do you need an RC circuit to get the internal oscillator to work?
3. If so what values of R and C would produce 4Mhz?
If you dont require the RC could somone please show me how to set up the OSCCON register so as to use the internal oscilllator.
