Absolute Address: When data is accessed by absolute address, the value already in the absolute

address is placed in the memory table. Loading the immediate data when the instruction is

executed transfers that value to the register and the data is accessed in the indirect register

addressing mode.

@(disp,PC),R1

MOV.B

@R1,R0

.DATA.L H'12345678

MOV.B @H'12345678,R0

16-Bit/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. Loading the immediate data when the

instruction is executed transfers that value to the register and the data is accessed in the indirect

indexed register addressing mode.
