Immediate Data: 8-bit immediate data is placed in the instruction code. Word and longword

immediate data is not placed in the instruction code. It is placed in a table in memory. The table in

memory is accessed with the MOV immediate data instruction using PC relative addressing mode

with displacement.

Note:

Immediate data is accessed by @(disp,PC).

Absolute Addresses: When data is accessed by absolute address, place the absolute address value

in a table in memory beforehand. The absolute address value is transferred to a register using the

method whereby immediate data is loaded when an instruction is executed, and the data is

accessed using the register indirect addressing mode.

Note:

Immediate data is referenced by @(disp,PC).

16-Bit/32-Bit Displacement: When data is accessed using the 16- or 32-bit displacement

addressing mode, 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 accessed using index register indirect addressing mode.
