Figure: LGF_PulseRelay Signal diagram
trigger changes the Boolean value of the output out.set sets the Bboolean value of the output out to TRUE.reset sets the Boolean value of the output out to FALSE.set and reset are set in the same cycle, the reset input has priority.The block can also be used as a frequency divider. If the input trigger is supplied with a fixed frequency, the output out delivers half the frequency.
