18.2.1

PROM Mode Setting

In PROM mode, the H8/3048 (H8/3048ZTAT) 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.

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.
Table 18.3 Socket Adapter
Microcontroller
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.
