during instruction execution.
3.4.1
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 PD78F0711 and 78F0712 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.
Operand Address Addressing
MULU
DIVUW
ADJBA/ADJBS
ROR4/ROL4
Implied addressing
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
