The time Ta (the current time in xLogic) is triggered with the 0 to 1 transition at input Trg.
If the status at input Trg stays 1 at least for the duration of the configured time T, the output
is set to 1 when this time has expired (the on signal of the output follows the on signal of the
input with delay).
The time is reset if the status at input Trg changes to 0 again before the time T has expired.
The output is reset to 0 when input Trg is 0.
