6.2 H8/3834 PROM Mode
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
HN27C256. Table 6.1 shows how to set the chip to PROM mode.

6.2.2 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 28 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.
