APPENDIX A. TABLE OF INSTRUCTION USABLE WITH EVAKIT-75X ONLY

APPENDIX A. TABLE OF INSTRUCTION USABLE WITH EVAKIT-75X ONLY

Since EVAKIT-75X (75X series common evaluation board) supports the 75X series functions, it can execute the following instructions not available with the μPD75402A. Since the μPD75402A and μPD75P402 cannot execute these instructions even though they can be executed on the EVAKIT, do not use them.
