18.11 Notes on Ordering Masked ROM Version Chip
When ordering the H8/3048 Series chips with a masked ROM, note the following.
•
•
(ROM: 128 kbytes)
H'00000–1FFFF
Note: * Program H'FF to all addresses in these areas.
When ordering through an EPROM, use a 128-kbyte one.
Fill all the unused addresses with H'FF as shown in figure 18-33 to make the ROM data size
128 kbytes for all H8/3048 Series chips, which incorporate different sizes of ROM. This
applies to ordering through an EPROM and through electrical data transfer.
