Function "4: bOut = f (Truth table)"
When the function "4: bOut = f (truth table)" is selected in

C00820

, the output value bOut depends

on the truth table parameterised in

C00821/1...8

.

The following table shows which setting may be required in

C00821/1...8

to realise the logic

operations NAND, NOR, XOR and XNOR:

C00821/1...8

Truth table for function "4: bOut = f

(truth table)"

• Each of the eight possible input

combinations can be assigned to

the output value FALSE or TRUE.

• For an application example see

the following section.

0 FALSE
1 TRUE
