[Function]
[Operand format]
[Description example]
[Illustration]
The memory to be manipulated is directly addressed with immediate data in an instruction word becoming an
operand address.
This addressing can be carried out for all of the memory spaces. However, before addressing a memory bank
that is not set by the memory bank select register (BANK), change the setting of the memory bank by using
BANK.
