Note: @(disp,PC) accesses the immediate data.
16-Bit/32-Bit Displacement: When data is accessed by 16-bit or 32-bit displacement, the
displacement value is placed in the memory table in advance. That value is transferred to the
register by loading the immediate data during the execution of the instruction, and the data is
accessed in the indirect indexed register addressing mode.
