Setting PLL for 18F14k22

[Fanie]

I only get 16MHz, but would like the PLL to run it at 64MHz.  Tested with the LED method, four times slower.

It's probably going to be one of the stupid settings I miss.

   FOSC = IRC ; Internal RC oscillator
   'FOSC = HS      ; HS oscillator                     Neither of these makes a difference...

Try this:

Code Select Expand

Device = 18F14K22
Declare Xtal = 64

Main:
    OSCCON = 0x72       'Set Internal Oscillator Frequency to 16 MHz and select Internal oscillator block
    OSCTUNE.6 = 1       'PLL enabled (for HFINTOSC 8 MHz and 16 MHz only)
End
