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.
