[Function]
[Operand format]
Instructions for accessing registers (such as accumulators) that have special functions are directly specified with the
instruction word, without using any register specification field in the instruction word.
Because implied addressing can be automatically employed with an instruction, no particular operand format
is necessary.
Implied addressing can be applied only to MULU X.
Register addressing accesses a general-purpose register as an operand. The instruction word of 3-bit long is used
to select an 8-bit register and the instruction word of 2-bit long is used to select a 16-bit register.
