TTABLE input combinations
The function has four inputs, and therefore 16 combinations. These combinations
can be found in a truth table; for each combination, the output value can be
adjusted. The number of configurable combinations depends on the number of
inputs connected to the function. For example:
Number In3 In2 In1 In0
0 0 0 0 0
1 0 0 0 1
2 0 0 1 0
3 0 0 1 1
4 0 1 0 0
5 0 1 0 1
6 0 1 1 0
7 0 1 1 1
8 1 0 0 0
9 1 0 0 1
10 1 0 1 0
11 1 0 1 1
12 1 1 0 0
13 1 1 0 1
14 1 1 1 0
15 1 1 1 1
