Pulse stretching
Pulse stretching is a function for changing a digital input signal. A pulse on a digital input is
stretched to at least the configured length. If the input pulse is already longer than the
configured length, the pulse is not changed.
Principle of pulse stretching
The figure below uses examples to show whether and how input pulses are changed.
