    Another thought...
    I'm running the 16F628A at 5.0V DC. After looking at the electrical information, it seems that I should be running it at 3.5V. This would run the internal oscillator at a more precise speed. Is this correct?
    Please make sure I'm getting this right.
    5V supply... 3.5V drop across the PIC... Voltage drop of 1.5V... PIC runs at 150mA
    R = V / I
    R = 1.5 / .15
    R = 10 ohms (1/4 watt)
    What electrical information is telling you to run it at 3.5v?
    If you're talking about parameter F13, that's for 'jitter' not 'accuracy'.
