78 / 80 page ![]() HD404339 Series 76 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 HD404334 and HD404336 as an 8-kword version (HD404338), and to create the same data size for the HD4043312 as a 16-kword version (HD404339). The 8-kword and 16-kword data sizes are required to change ROM data to mask manufacturing 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.
