    using a 18f46k80 , but i would think any of simular series would have this as well

    again it very rare for me to use a pic at such a low osc rate and this where i found the problem for the calculations

    Can you post your currently used config bits, OSCCON, OSCCON2 and OSCTUNE settings?

    from the data sheet osc section




    Section 3.6.2 “INTPLL Modes”

    . Care should be taken
    that the PLL is enabled only if the HF-INTOSC
    postscaler is configured for 4 MHz, 8 MHz or 16 MHz

    Just where I was headed Richard, hence my question.
    The registers/config bits would show how he is setting up the clock.
