15.11 Notes on Ordering Mask ROM Version Chip
When ordering the H8/3039 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 figure15.29 to make the ROM data size
128 kbytes for all H8/3039 Group chips, which incorporate different sizes of ROM. This
applies to ordering through an EPROM and through electrical data transfer.
• The flash memory versions only registers for flash memory control (FLMCR, EBR, RAMCR,
and FLMSR) are not provided in the mask ROM versions. Reading the corresponding
addresses in a mask ROM version will always return 1s, and writes to these addresses are
disabled. This must be borne in mind when switching from the flash memory versions to a
mask ROM version.
