    - #### createZeroMask

          public static String createZeroMask(int size,
                                              int lsb,
                                              int msb)

      Create a mask of `size` bits, where the bits from the inclusive range `[lsb, msb]` are set to `0` and the rest are set to `1`.
      Parameters:
        `size` - The mask size
        `lsb` - The least significant bit index
        `msb` - The most significant bit index
      Returns:
        A mask string

    - #### createOneMask

          public static String createOneMask(int size,
                                             int lsb,
                                             int msb)

      Create a mask of `size` bits, where the bits from the inclusive range `[lsb, msb]` are set to `0` and the rest are set to `1`.
      Parameters:
        `size` - The mask size
        `lsb` - The least significant bit index
        `msb` - The most significant bit index
      Returns:
        A mask string
