Appendix E Instruction List
Note:
"2/1" of CYCLE number is following;
2: branching
1: not branching
The assembler calculates and sets values as follows in the rel11 and rel8 fields for hardware specifications.
(label12-PC-2)/2rel11, (label9-PC-2)/2rel8, label12, label9 are with sign.
When executing RETI instruction, S flag is required to be "0".

Note:
The assembler calculates and sets values as follows in the rel11 and rel8 fields for hardware specifications.
(label12-PC-2)/2->rel11, (label9-PC-2)/2rel8, label12, label9 are with sign.
In terms of delayed branches, branching must be implemented after executing the next command (delay slot).
Commands that can be placed at the delay slot are all 1 cycle, a, b, c, and d cycle commands.
Two or more-cycle instruction cannot be put.
