5.1.5 Data memory addressing
of the register or memory relevant to the execution of instructions.
the PD780024A, 780034A, 780024AY, and 780034AY Subseries, 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. Correspondence between data memory
and addressing is illustrated in Figures 5-6 to 5-10. For the details of each addressing mode, see 5.4 Operand
Address Addressing.
Addressing refers to the method of specifying the address of the instruction to be executed next or the address
