PROM Mode

16.4.1

PROM Mode Setting

The PROM version of the H8S/2245 Group suspends its microcontroller functions when placed in

PROM mode, enabling the on-chip PROM to be programmed. This programming can be done

with a PROM programmer set up in the same way as for the HN27C101 EPROM (V

PP = 12.5 V).

Use of a 100-pin/32-pin socket adapter enables programming with a commercial PROM

programmer.

Note that the PROM programmer should not be set to page mode as the H8S/2245 Group does not

support page programming.

Table 16.3 shows how PROM mode is selected.

Socket Adapter and Memory Map

Programs can be written and verified by attaching a 100-pin/32-pin socket adapter to the PROM

programmer. Table 16.4 gives ordering information for the socket adapter, and figure 16.2 shows

the wiring of the socket adapter. Figure 16.3 shows the memory map in PROM mode.
