    Smile save on power down

    The PIC16F628 has voltage comparators that can cause an interrupt. In the schematic the programmable reference is compared against a division of the input voltage. If input power falls dangerously low then an interrupt is generated.

    I do not see a way of monitoring supply voltage with out using a pin.

    Good luck!
