When ordering H8/3048B with mask ROM, note the following.
1. When ordering by means of an EPROM, use a 128-kbyte one.
2. Fill all unused addresses with H'FF and order the same ROM data size as for the 128-kbyte
3. The flash memory control registers (FLMCR, EBR, RAMCR, FLMSR, FLMCR1, FLMCR2,

version. This applies to ordering by means of an EPROM and by means of data transmission.
EBR1, and EBR2)used by the versions with on-chip flash memory 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 a flash memory version to a mask ROM version.
Notes on Ordering Mask ROM Version Chips
Note: * Write H'FF data in all addresses in this area.
