11. INSTRUCTION SET
(1) Operand identifier and its descriptive method
The operands are described in the operand column of each instruction according to the descriptive method for
the operand format of the appropriate instructions. (For details, refer to the
RA75X Assembler Package User's
Manual: Language
(EEU-1363).) For descriptions in which alternatives exist, one element should be selected.
Capital letters and plus and minus signs are keywords; therefore, they should be described as they are.
For immediate data, the appropriate numerical values or labels should be described.
The symbols of register flags can be used as a label instead of mem, fmem, pmem, and bit. (For details, refer
to
the
μ
PD750108 User’s Manual
(U11330E).) However, there are some restrictions on usable labels for fmem
and pmem.
Note
Only even address can be specified for 8-bit data processing.
