3.1.4 Data memory addressing
manipulation as efficient as possible. In the area that holds data memory (FD00H to FFFFH) especially, specific
modes of addressing that correspond to the particular function of an area, such as the special function registers (SFR)
or general-purpose registers, are available. Figures 3-5 through 3-8 show the data memory addressing modes.
