3.2 Operand Address Addressing
during instruction execution.
3.2.1 Implied addressing
The following methods are available to specify the register and memory (addressing) to undergo manipulation
[Function]
[Operand format]
[Description example]
This addressing automatically specifies the address of the registers that function as an accumulator (A and
AX) in the general-purpose register area.
Of the 78K/0 Series 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 x 8-bit multiply instruction, the product of the A register and X register is stored in AX. In this
example, the A and AX registers are specified by implied addressing.
MULU
DIVUW
ADJBA/ADJBS
ROR4/ROL4
Instruction
A register for multiplicand and AX register for product storage
AX register for dividend and quotient storage
A register for storage of numeric values targeted for decimal correction
A register for storage of digit data that undergoes digit rotation
