APPENDIX B Instructions
Note:
When an external data bus is used, the cycle counts during which an instruction is made to wait by
ready input or automatic ready must also be added.
Notes:
•
When an external data bus is used, the cycle counts during which an instruction is made to wait
by ready input or automatic ready must also be added.
•
Actually, instruction execution is not delayed by every instruction fetch. Therefore, use the
correction values to calculate the worst case.
