9.4.1.7. XNOR
A logical XNOR produces an output of “1” (TRUE) if the number of
inputs that are “1” (TRUE) is even or if all inputs are “0” (FALSE).

Parameter
Inputs number: You can set 2 to 8 inputs using this option.
9.4.1.8. Logical macro
This operator permits the grouping of two or three logic blocks.
A maximum of 8 inputs are available.
The result of the first two operators flows into a third operator; the
result of this operator is output on the OUTPUT output.

Parameter
Input Logic 1, 2: Use this option to set the number of logic inputs
(1 to 7).
If one of the two logic inputs has only one input, the corresponding
logic is deactivated and the input is assigned directly to the final logic
(example in the adjacent figure).
Select logic 1, 2, 3: Permits the selection of the type of operator from
the following options: AND, NAND, OR, NOR, XOR, XNOR.
Enable OUT1, OUT2: Select this option to display intermediate results.
(See figure above).
