PD78F9418 is provided with a wide range of addressing modes to make memory manipulation as efficient
as possible. A data memory area (FD00H to FFFFH) can be accessed using a unique addressing mode according to
its use, such as a special function register (SFR). Figure 5-2 illustrates the data memory addressing modes.
