completely restarts the timer. The programmed time is used as the current time
for the restart. A change in the RLO from 1 to 0 at the enable input has no effect.
(2) If the RLO changes from 0 to 1 at the enable input while the timer is not running
and there is still an RLO of 1 at the start input, the timer will also be started as a
pulse with the time programmed.
(3) A change in the RLO from 0 to 1 at the enable input while there is still an RLO of
