Note
You can invert individual inputs of the basic and special functions;
that is, if an input carries a logical “1” signal, the circuit program will
output a logical “0”. On the other hand, a logical -0" is inverted into
a logical “1” signal.
To invert an input, move the cursor to the relevant position,
