Exclusive OR function block (XO)
The exclusive OR function XOR is used to generate combinatory expressions with boolean vari-
ables. The function block XOR has two inputs and two outputs. One of the outputs is inverted.
The output signal is 1 if the input signals are different and 0 if they are equal.

Set-reset function block (SR)
The Set-Reset (SR) function is a flip-flop that can set or reset an output from two inputs respec-
tively. Each SR function block has two outputs, where one is inverted.
