and begin charging of the condenser connected TC pin.
When TC pin reaches 2.7V (V

); the condenser connected TC pin begin discharge, and the
Reset pin outputs "Low". During the Reset outputs "High" for the first time; the time of charge will
be t

since TC pin begin charging its condenser starting from 0V.
When TC pin drops to 0.2V (V
TH2(L)
); the Reset will outputs "High" again. At same time, TC pin will
begin charging again. Unless correct clock input is given to WD pin, the TC pin will repeats the
charging from 0.2V to 2.7V, and the Reset will also repeats "High" during the t
WD
cycle, and "Low"
during t
RT(2)
cycle.
When correct clock input is given to WD pin before TC pin reaches 2.7V, the Reset holds "High"
output.
When incorrect clock is given to WD pin, the TC pin will repeats the charging from 0.2V to 2.7V, and
the Reset will also repeats "High" during the t
WD
cycle, and "Low" during t
RT(2)
cycle.
When V

drops down to 4.25V (V

), the Reset circuit will function, and it will output "Low" to
Reset pin and TC pin changes to discharging state.
