9. Instruction Set
(1) Operand identifier and description method
In the operand column of each instruction, describe the
corresponding operand in accordance with the de-
scription method for the operand identifier of the in-
struction (refer to the "
RA75X Assembler Package User's
Manual Language Volume" (EEU-730)
for details). If
more than one description method is available, select
one of them. Capital alphabetic letters, plus and minus
signs are key words. Describe them as they are.
In the case of immediate data, describe appropriate
numeric values or labels.
Symbols of various registers and flags can be de-
scribed as labels instead of mem, fmem, pmem, bit, etc.
(Refer to the "
μ
PD751
××
Series User’s Manual (IEM-
922)
" for details). Labels which can be described are
limited for fmem and pmem.
