A TRANSITIONS ON WDI IGNORED DURING SETUP DELAY.
B TRANSITION(S) ON WDI IGNORED DURING STARTUP DELAY PERIOD.
C WATCHDOG TIMER STARTS AFTER STARTUP DELAY AND WDO IS DEASSERTED.
D TRANSITION OCCURS BEFORE WATCHDOG TIMEOUT PERIOD. WATCHDOG
TIMER CLEARS AND STARTS TIMER AGAIN.
E WATCHDOG TIMES OUT, WDO ASSERTS.
F TRANSITIONS ON WDI IGNORED WHEN WDO ASSERTED.
G WATCHDOG TIMER STARTS AFTER WDO DEASSERTS.

? Watchdog Timeout Period:
Normal operating watchdog timeout period after the
initial startup delay.
A watchdog output pulse is asserted if a valid watch-
dog input transition is not received before the timeout
period elapses.
Eight pin-selectable timeout period options for each
device, from 30μs to 60s.
Pin-selectable watchdog timer disable feature.

? Watchdog Output/Timing Options:
Open drain, active low with 100ms minimum watch-
dog output pulse (MAX6369/MAX6371/MAX6373).
Push-pull, active low with 1ms minimum watchdog
output pulse (MAX6370/MAX6372/MAX6374).
Each device has a watchdog startup delay that is initi-
ated when the supervisor is first powered or after the
user modifies any of the logic control set inputs. The
watchdog timer does not begin to count down until the
