3.4 Operand Address Addressing
during instruction execution.
3.4.1 Implied addressing
72
The following methods are available to specify the register and memory (addressing) to undergo manipulation
[Function]
[Operand format]
[Description example]
The register that functions as an accumulator (A and AX) among the general-purpose registers is automatically
(implicitly) addressed.
Of the 78K0/LF2 instruction words, the following instructions employ implied addressing.
Because implied addressing can be automatically employed with an instruction, no particular operand format is
necessary.
In the case of MULU X
With an 8-bit
the A and AX registers are specified by implied addressing.
MULU
DIVUW
ADJBA/ADJBS
ROR4/ROL4
Instruction
8-bit multiply instruction, the product of A register and X register is stored in AX. In this example,
AX register for dividend and quotient storage
A register for multiplicand and AX register for product storage
A register for storage of numeric values that become decimal correction targets
A register for storage of digit data that undergoes digit rotation
