After switching on, the device will not function properly until there is at least one rising edge at
the input.
4.2.2 Input configuration: edge-controlled
The edge of the input signal is the trigger for the output of pulses at the output. The duration of the
output pulse is always constant and is determined by the parameter [h.t1] or [h.t2]. The trigger can be
set to either the positive or negative edge.
