11. INSTRUCTION SET
(1) Expression formats and description methods of operands
The operand is written in the operand column of each instruction in accordance with the method of use
of the instruction operand identifier. For details, refer to “
RA75X ASSEMBLER PACKAGE USER’S
MANUAL—LANGUAGE (U12385E)
”. If there are several elements, one of them is selected. Capital letters
and the + and – symbols are key words and are written as they are.
For immediate data, appropriate numbers and labels are written.
Instead of the labels such as mem, fmem, pmem, and bit, the symbols of the registers can be written.
However, there are restrictions in the labels that can be written for fmem and pmem. For details, refer to
User’s Manual (U12020E)
