Notes on ROM Out
Please note the following when ordering HD404668, HD4046612, HD40A4668, or HD40A46612 ROM.
On ROM out, fill the ROM area indicated below with 1s to create the same data size as a 16-kword version
(HD404669, HD40A4669). A 16-kword data size is required to change ROM data to mask manufacturing
data since the program used is for a 16-kword version.
This limitation applies when using an EPROM or a data base.
