Parameter
Function "4: bOut = f (Truth table)"
When the function "4: bOut = f (truth table)" is selected in
, the output value bOut depends
on the truth table parameterised in
The following table shows which setting may be required in
to realise the logic
operations NAND, NOR, XOR and XNOR:

Info
Function selection
0 bOut = 0
Constant value "FALSE"
1 bOut = 1
Constant value "TRUE"
2 bOut = bIn1 AND bIn2
AND operation
3 bOut = bIn1 OR bIn2
OR operation
4 bOut = f (truth table)
The output value depends on the
truth table parameterised in
