Notes on Ordering Mask ROM Version Chips
When ordering H8/3064 with mask ROM, note the following.
1. When ordering by means of an EPROM, use a 512-kbyte one.
2. Fill all unused addresses with H'FF as shown in figure 18.20 to make the ROM data size 512-
kbytes for the H8/3064 mask ROM version. This applies to ordering by means of an EPROM
and by means of data transmission.

Figure 18.20 Mask ROM Addresses and Data
3. The flash memory control registers (FLMCR, EBR, RAMCR, FLMSR, FLMCR1, FLMCR2,
EBR1, and EBR2) used by the versions with on-chip flash memory are not provided in the
mask ROM version. 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.
