Section 2 CPU
Absolute Address: When data is accessed by absolute address, the value in the absolute address 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
register addressing mode.
Table 2.6
Classification
Absolute address
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.
Table 2.7
Classification
16-bit displacement
Note: @(disp,PC) accesses the immediate data.

Table 2.8 describes addressing modes and effective address calculation.
