Function 2: Evaluate rising and falling signal edges

Pulse duration
[16-26] Switching performance for function selection "2: High and low edge"
Functional sequence
1. A signal change (FALSE/TRUE edge or TRUE/FALSE edge) at the bIn input sets the bOut
output to TRUE.
2. After the parameterised pulse duration has elapsed, the bOut output is reset to FALSE
unless another signal change has taken place at the bIn input.
– In case of another signal change at the input bIn, the pulse time restarts to elapse,
i.e. the output bOut can be retriggered.
