A function block groups an algorithm and a set of private data. It has inputs and outputs. - Flipflop bistable.
Inputs
IN : BOOL Swap
command (on rising edgeA rising edge is the transition of a digital signal from low to high. It is also called positive edge)
RST : BOOL Reset to FALSE
Outputs
Q : BOOL Output
Remarks
The output is systematically reset to FALSE if RST is TRUE.
The output changes on each rising edge of the IN input, if RST is FALSE.
