the Power Fail circuitry. If a resistive divider is connected from

the voltage to be monitored to the PFI input, the PFO will go

LOW if the voltage at PFI goes below 1.25V reference. Should

hysteresis be desired, connect a resistor (equal to

approximately 10 times the sum of the two resistors in the

divider) between the PFI and PFO pins. A capacitor between

PFI and GND will reduce circuit sensitivity to input high

frequency noise. If it is desired to assert a reset in addition to

the PFO flag, this may be achieved by connecting the PFO

output to MR.
