unconnected or connect to V CC if unused. WDO deasserts
when MR is low (MAX6701(A)/MAX6702(A)/MAX6703(A)/
MAX6705(A)/ MAX6706(A)/MAX6707(A) only).

PFO
Power-Fail Monitor Output. Open drain or push-pull active low.
PFO goes low when PFI is less than 0.62V.
Watchdog Input. If WDI remains high or low for longer than the
watchdog timeout period, the internal watchdog timer runs out and
WDO is asserted. WDO is asserted low after each watchdog
overflow and remains low until the watchdog timer is cleared (the
reset output is not affected). The internal watchdog timer clears

WDI
whenever a V CC /RST_IN1/RST_IN2 reset is asserted, the manual
reset is asserted, or WDI sees a rising or falling edge. The
watchdog timer remains cleared until the reset output is
deasserted. On the MAX6704, RESET pulse asserts for the reset
timeout period after each watchdog timeout overflow. The
watchdog timer cannot be disabled.

the reset timeout period after the reset conditions are terminated.
