18.13 Notes on Ordering Mask ROM Version

When ordering the mask ROM version of the H8/3028 Group, note the following.

1. When ordering using an EPROM, use a 512-kbyte EPROM.

2. Fill the address area shown in figure 18.20 below with H'FF as shown to make the ROM data

size 512 kbytes. This applies both to ordering using an EPROM and to ordering using

electrical data transfer.

3. The flash memory control registers (RAMCR, FLMCR1, FLMCR2, EBR1, EBR2) are not

provided in the mask ROM version. Reading these addresses always returns a value of 1, and it

is not possible to write to them. This must be borne in mind when switching from the flash

memory version to the mask ROM version.
