Functionality
F_TRIG is used as a falling edge detector.
The function detects the transition from TRUE to FALSE at the CLK input. When the
falling edge is detected, the element assigns the Q output to TRUE. At the next execution
round, the output is returned to FALSE despite the state of the input.
