Literal Constant: Byte literal constant is placed inside the instruction code as immediate data.
Since the instruction length is fixed to 16 bits, word and longword literal constant is not placed
inside the instruction code, but in a table in memory. The table in memory is referenced with a
MOV instruction using PC-relative addressing mode with displacement.
Example: MOV.W @(disp, PC)
Absolute Addresses: When data is referenced by absolute address, the absolute address value is
placed in a table in memory beforehand as well as word or longword literal constant. 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 word or
longword 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.
