PROM Mode (H8/3887, H8/3847)
6.2.1
Setting to PROM Mode
If the on-chip ROM is PROM, setting the chip to PROM mode stops operation as a
microcontroller and allows the PROM to be programmed in the same way as the standard
HN27C101 EPROM. However, page programming is not supported. Table 6-1 shows how to set
the chip to PROM mode.

Socket Adapter Pin Arrangement and Memory Map
A standard PROM programmer can be used to program the PROM. A socket adapter is required
for conversion to 32 pins, as listed in table 6-2.
Figure 6-2 shows the pin-to-pin wiring of the socket adapter. Figure 6-3 shows a memory map.
