11. INSTRUCTION SET
(1) Expression formats and description methods of operands
The operand is described in the operand column of each instruction in accordance with the description
method for the operand expression format of the instruction. 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 described as they are.
For immediate data, appropriate numbers or labels are described.
Instead of the labels such as mem, fmem, pmem, and bit, the symbols of the register flags can be described.
However, there are restrictions in the labels that can be described for fmem and pmem. For details, see
PD750068 User’s Manual (U10670E).
