    Note with the DEFINE OSC 20 ... PAUSE and PAUSEUS will still give the "written" time.

    For 20Mhz, you'll also need to change the oscillator config to HS.

    please go thro the datasheet Ds35007B in respect of PIC16F84A-4/20-- figures 9-1 and 9-2 and relevent comments. it is however possible as per the datasheet but voltage restrictions apply , i beleive.

    for PIC16F628A, it is possible to have any crystal.

    In both cases appropriate config commet to be moddedas you know already
