possible. The area (FE00H to FEFFH) which contains a data memory and the special function register area (SFR)
can be accessed using a unique addressing mode in accordance with each function. Figures 3-3 and 3-4 illustrate the
data memory addressing.
Special function registers (SFRs) of on-chip peripheral hardware are allocated to the area of FF00H to FFFFH (see
The 78K0S/KB1+ is provided with a wide range of addressing modes to make memory manipulation as efficient as
