3.1.4 Data memory addressing
the register or memory relevant to the execution of instructions.
78K0/KC1+, based on operability and other considerations. For areas containing data memory in particular, special
addressing methods designed for the functions of special function registers (SFR) and general-purpose registers are
available for use. Figures 3-5 to 3-8 show correspondence between data memory and addressing. For the details of
each addressing mode, see 3.4 Operand Address Addressing.
Addressing refers to the method of specifying the address of the instruction to be executed next or the address of
Several addressing modes are provided for addressing the memory relevant to the execution of instructions for the
