Notes on Ordering Mask ROM Version Chip

When ordering the H8/3048 Group chips with a mask ROM, note the following.
• When ordering through an EPROM, use a 128-kbyte one.
• Fill all the unused addresses with H'FF as shown in figure 18.7 to make the ROM data size 128
kbytes for all H8/3048 Group chips, which incorporate different sizes of ROM. This applies to
ordering through an EPROM and through electrical data transfer.
