6.2.1
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 EPROM. Table 6.1 shows how to set the chip to PROM mode.

6.2.2
A general-purpose 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.
