APPENDIX A Instruction Lists
Notes:
• The field "rel8" in the TYPE-D instruction format and the field "rel11" in the TYPE-F format have
the following relation to the values "label9" and "label12" in assembly notation.
label9
→ rel8=(label9 – PC – 2)/2
label12
→ rel11=(label12 – PC – 2)/2
• The value "2/1" in the cycle(CYC) column indicates "2" cycles if branching, "1" if not branching.
• It is necessary to set the S flag to "0" for RETI execution.
