saving current while using the watchdog
WDI is internally driven low during the first 7/8 of the watchdog time-out period, then momentarily pulses high,
resetting the watchdog counter. For minimum watchdog input current (minimum overall power consumption), leave
WDI low for the majority of the watchdog time-out period, pulsing it low-high-low once within 7/8 of the watchdog
time-out period to reset the watchdog timer. If, instead, WDI is externally driven high for the majority of the time-out
period, a current of 5 V/40 k
Ω ≈ 125 µA can flow into WDI.

power-fail comparator (PFI and PFO)
An additional comparator is provided to monitor voltages other than the nominal supply voltage. The power-fail-input
(PFI) is compared with an internal voltage reference of 1.25 V. If the input voltage falls below the power-fail threshold
(VPFI) of 1.25 V (typ), the power-fail output (PFO) goes low. If PFO goes above 1.25 V plus about 10−mV hysteresis,
the output returns to high. By connecting two external resistors, it is possible to supervise any voltages above 1.25 V.
The sum of both resistors should be approximately 1 M
Ω, to minimize power consumption and also to ensure that the
current in the PFI pin can be neglected compared with the current through the resistor network. The tolerance of the
external resistors should be not more than 1% to ensure minimal variation of sensed voltage. If the power-fail
comparator is unused, connect PFI to ground and leave PFO unconnected.
