18.2.2
The H8/3437 and H8/3434 can be programmed with a general-purpose PROM programmer by
using a socket adapter to change the pin-out to 32 pins. See table 18.3. The same socket adapter
can be used for both the H8/3437 and H8/3434. Figure 18.2 shows the socket adapter pin
assignments.

The PROM size is 60 kbytes for the H8/3437 and 32 kbytes for the H8/3434. Figures 18.3 and
18.4 show memory maps of the H8/3437 and H8/3434 in writer mode. H'FF data should be
specified for unused address areas in the on-chip PROM.
When programming with a PROM programmer, limit the program address range to H'0000 to
H'F77F for the H8/3437 and H'0000 to H'7FFF for the H8/3434. Specify H'FF data for addresses
H'F780 and above (H8/3437) or H'8000 and above (H8/3434). If these addresses are programmed
by mistake, it may become impossible to program or verify the PROM data. The same problem
may occur if an attempt is made to program the chip in page programming mode. Note that the
PROM versions are one-time programmable (OTP) microcomputers, packaged in plastic
packages, and cannot be reprogrammed.
