Notes on ROM Out

Please pay attention to the following items regarding ROM out.

On ROM out, fill the ROM area indicated below with 1s to create the same data size for the HD404354,

HD40A4354, HD404356 and HD40A4356 as an 8-kword version (HD404358, HD40A4358). The 8-kword

and 16-kword data sizes are required to change ROM data to mask manu facturing data since the program

used is for an 8-k or 16-kword version.

This limitation applies when using an EPROM or a data base.
