Section 2 CPU
Absolute Addresses: When data is referenced by absolute address, the absolute address 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 register indirect addressing mode.

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.
