    an external integrated oscillator feeding Timer1 in capture mode ???

    using mains rectified to get a precise 100 ( or 120 ! ) Hz signal and measure the supposed 10 or 8.33 ms period ??? - "Pulsin" can be used here.

    one could even think to an auto-adjustment through the OSCTUNE register ... if intosc used.

    ...

    if only a rough idea is needed ... some RC external ladder with RC Time function ...

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!
