INSTRUCTION SET
(1) Operand identifier and description
The operand is described in the operand field of each instruction in accordance with the description for the
operand identifier of the instruction. (See the
RA75X Assembler Package User's Manual Language Volume
(EEU-730)
for details.) When there are multiple elements in the description, one of the elements is selected.
Upper case letters and symbols (+,–) are keywords and are described unchanged.
For immediate data, a suitable value or label is described.
Various register or flag symbols can be used as a label instead of mem, fmem, pmem, bit, etc. (See the
μ
PD75308 User’s Manual (IEM-5016)
for details). However, there are restrictions on the labels for which fmem
and pmem can be used (see the table on the previous page).
