18.2 PROM Mode
18.2.1 PROM Mode Setting
In PROM mode, the H8/3048 version with on-chip PROM suspends its microcontroller functions,
enabling the on-chip PROM to be programmed. The programming method is the same as for the
HN27C101, except that page programming is not supported. Table 18-2 indicates how to select
PROM mode.

18.2.2 Socket Adapter and Memory Map
The PROM is programmed using a general-purpose PROM programmer with a socket adapter to
convert to 32 pins. Table 18-3 lists the socket adapter for each package option. Figure 18-2 shows
the pin assignments of the socket adapter. Figure 18-3 shows a memory map in PROM mode.

H8/3048
The size of the H8/3048 PROM is 128 kbytes. Figure 18-3 shows a memory map in PROM mode.
H'FF data should be specified for unused address areas in the on-chip PROM.
When programming the H8/3048 with a PROM programmer, set the address range to H'00000 to
H'1FFFF.
