Notes:
• "2/1" under CYCLE indicates 2 when branching occurs and 1 when branching does not occur.
• In the rel11 and rel8 fields of the hardware specifications, the assembler calculates values and sets them as shown below:
(label12-PC-2)/2 → rel11, (label9-PC-2)/2 → rel8; label12 and label9 have a sign.
• To execute the RETI instruction, the S flag must be 0.
