Notes On ROM Out
Please pay attention to the following items regard ing ROM out.
On ROM out, fill the ROM area indicated below with 1s to create the same data size as 4-kword version
(HD404654). A 4-kword data size is required to change ROM data to mask manufacturing data since the
program used is for a 4-kword version.
This limitation applies when using an EPROM or a data base.
Fill this area with all 1s
