Function 0: Evaluate rising signal edges

Pulse duration
[16-24] Switching performance for function selection "0: High edge"
Functional sequence
1. A FALSE-TRUE 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 FALSE/TRUE edge has been set at the bIn input.
– If an additional FALSE-TRUE edge occurs at the bIn input, the pulse duration starts
again from the beginning, i.e. the bOut output can be retriggered.
16.1.44.2 Function 1: Evaluate falling signal edges
Pulse duration
[16-25] Switching performance for function selection "1: Low edge"
Functional sequence
1. A TRUE-FALSE edge at the bIn inputs sets the bOut output to TRUE.
2. After the parameterised pulse duration has elapsed, the bOut output is reset to FALSE
unless another TRUE/FALSE edge has been set at the bIn input.
– If an additional TRUE-FALSE edge occurs at the bIn input, the pulse duration starts
again from the beginning, i.e. the bOut output can be retriggered.
