16-Bit/32-Bit Displacement: When data is referenced with a 16- or 32-bit displacement, the
displacement value is placed in a table in memory beforehand. Using the method whereby
immediate data is loaded when an instruction is executed, this value is transferred to a register and
the data is referenced using indexed register indirect addressing mode.
