    These hex values match the 16F818 as expected.

    from your code..........................
    'osccon values for 16f818/819:
    'OSCCON = $00 'for 31.25 khz
    'OSCCON = $10 '125khz
    'OSCCON = $20 '250khz
    'OSCCON = $30 '500khz
    'OSCCON = $40 '1mhz
    'OSCCON = $50 '2mhz
    OSCCON = $60 '4mhz 'set int osc to 4mhz
    'OSCCON = $70 '8mhz

    from the data sheet.....................
    bit 6-4 IRCF2:IRCF0: Internal Oscillator Frequency Select bits
    111 = 8 MHz (8 MHz source drives clock directly)
    110 = 4 MHz
    101 = 2 MHz
    100 = 1 MHz
    011 = 500 kHz
    010 = 250 kHz
    001 = 125 kHz
    000 = 31.25 kHz (INTRC source drives clock directly)

    I don't understand the issue?

    so I guess
    the clocking below 4Mhz cannot be used with HPWM ?

    Cause I need to get down to 50Hz, my choices is left with pulsout command.
    I'll see if I CAN use it on the same pin.
