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.
