Combinations of functions with less inputs than those shown are also supported. For example, combinations of
functions with the following number of inputs are supported: 4 and 3, 3 and 3, 3 and 2, 5 and 2, etc.

Normal mode provides complete backward compatibility with
four-input LUT architectures. Two independent functions of four inputs
or less can be implemented in one Arria GX ALM. In addition, a
five-input function and an independent three-input function can be
implemented without sharing inputs.
