The Logical Bus Operator block performs logical operations on a bus such as
AND, OR, XOR, and invert. You can perform masking by entering a mask value in
decimal notation, or a shift (rotate) operation by entering the number of bits. By
default, a right shift operation preserves the input data sign (for signed inputs).
