H8/38024 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
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.
Figure 6.2 shows the pin-to-pin wiring of the socket adapter. Figure 6.3 shows a memory map.
