7. INSTRUCTION SET
(1) Representation and coding formats for operands
In the instruction’s operand area, use the following coding format to describe operands corresponding to the instruction’s
operand representations (for further description, refer to the RA75X Assembler Package User’s Manual Language
(EEU-1363)). When there are several codes, select and use just one. Codes that consist of upper-case letters and + or
– symbols are key words that should be entered as they are.
For immediate data, enter an appropriate numerical value or label.
Enter register flag symbols as label descriptors instead of mem, fmem, pmem, bit, etc. (for further description, refer to the
User’s Manual). The number of labels that can be entered for fmem and pmem are restricted.
