The timer is active when the Set signal ( S ) is true.
The output ( Q ) of the timer rises up when S becomes true and remains high
for PV seconds.
If the Set signal become false while counting, the timer stops and the output become false.
If the Reset signal ( R ) becomes true, the output becomes false and the timer stops.

The timer is actived when the set signal ( S ) becomes true (on the rising edge of S ).
The output ( Q ) of the timer rises up when S becomes true and remains
high for PV seconds.
If the Set signal become false while counting, the timer does not stop.
If the reset signal ( R ) becomes true (a rising edge is detected) the output becomes false and the timer stops.

The timer is active after the set signal ( S ) becomes true.
The output ( Q ) of the timer rises up PV seconds after the
Set ( S ) becomes true.
If the Set signal becomes false while counting, the timer stops and the output remains false.
If the Reset signal ( R ) becomes true, the output remains false and the timer stops.

The timer is active after a rising edge of the set signal ( S ).
The output ( Q ) of the timer rises up PV seconds after the Set ( S )
becomes true.
If the Set signal become false while counting, the timer does not stop.
If the Reset signal ( R ) becomes true, the output remains false and the timer stops.

The timer is active after a falling edge of the set signal ( S ).
The output ( Q ) of the timer rises up PV seconds after the
Set ( S ) becomes false (falling edge).
If the Set signal become true while counting, the timer does not stop.
If the Reset signal ( R ) has a rising edge, the output remains false and the timer stops.
