3.1.4 Data memory addressing
as possible. The area (FE80H to FEFFH) which contains a data memory and the special function register (SFR) area
can be accessed using a unique addressing mode in accordance with each function. Figures 3-4 to 3-6 illustrate the
data memory addressing.
128-byte internal high-speed RAM is provided in the 78K0S/KU1+.
The internal high-speed RAM can also be used as a stack memory.
Special function registers (SFRs) of on-chip peripheral hardware are allocated to the area of FF00H to FFFFH (see
The 78K0S/KU1+ are provided with a wide range of addressing modes to make memory manipulation as efficient
