Note: The address of the immediate data is accessed by @(disp, PC).
Absolute Address: When data is accessed by absolute address, the value already in the absolute
address is placed in the memory table. By loading the immediate data when the instruction is
executed, that value is transferred to the register and the data is accessed in the indirect register
addressing mode.

Note: The address of the immediate data is accessed by @(disp, PC).
16/32-Bit Displacement: When data is accessed by 16-bit or 32-bit displacement, the pre-existing
displacement value is placed in the memory table. By loading the immediate data when the
instruction is executed, that value is transferred to the register and the data is accessed in the
indirect indexed register addressing mode.
