Note on ROM Ordering
Please note the following when ordering HD404372, HD40A4372, HD40C4372, HD404382, HD40A4382
and HD40C4382 ROM.
When ordering ROM, please fill the "Not used" areas below with all-1 data, to give the same amount of
data as for the 4-kwords version (HD404374, HD40A4374, HD40C4372, HD404384, HD40A4384,
HD40C4384). The program that converts ROM data to mask drawing data is the same as that used for the
4-kwords version, and therefore the same amount of data is necessary. This applies both to orders using
EPROM and orders using data transmission.
