    Hi, Daniel

    I generally use TMR1 and it's interrupt, reading Timer1 ( as free running timer ) ...

    just read it @ each interrupt ... difference from previous read ... gives the period.

    @ 20 Mhz max resolution is 200ns which is quite enough ...

    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 " !!!
