At any point during the operation of the Timer, if it detects a true level
on the Reset input, it will disable the Timer and set the output to false.
The Timer must again be triggered by a false to true transition on the
input. This means that if the input is true and the Timer is reset, the
Timer will remain inactive. Even if the Reset changes back to false
while the input is true, the Timer remains inactive. In order to start a
new pulse operation, the input must change to false and then back to
true. Refer to the illustration of the timer function for clarification.
