3.21.6.2 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.
