17.4.1
The PROM version of the H8S/2345 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
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/2345 does not
support page programming.
Table 17.4 shows how PROM mode is selected.

Programs can be written and verified by attaching a socket adapter to the PROM programmer to
convert from a 100-pin arrangement to a 32-pin arrangement. Table 17.5 gives ordering
information for the socket adapter, and figure 17.2 shows the wiring of the socket adapter. Figure
17.3 shows the memory map in PROM mode.
