Notes on Ordering Mask ROM Version Chips

When ordering H8/3062, H8/3061, and H8/3060 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 as shown in figure 17.20 to make the ROM data size 128-

kbytes for the H8/3062, H8/3061, and H8/3060 mask ROM versions, which incorporate

different sizes of ROM. This applies to ordering by means of an EPROM and by means of data

transmission.

(ROM: 128 kbytes)

H'00000–1FFFF

Note: * Write H'FF in all addresses in these areas.

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 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.

4. 5 V operation models of the H8/3064F-ZTAT and H8/3062F-ZTAT A-mask version with on-

chip flash memory have a V

therefore necessary regarding board design when switching to a mask ROM version.
