Notes: 1. Modes 6 and 7, the on-chip ROM available after a power-on reset is the 64-kbyte area comprising addresses
H'000000 to H'00FFFF.
Since the on-chip ROM area differs according to each product, see section 3.5, Memory Map in Each Operating
Mode.
2. In the H8S/2398 F-ZTAT, modes 2 and 3 indicate boot mode. For details on boot mode of H8S/2398 F-ZTAT,
refer to table 19-35 in section 19.17, On-Board Programming Modes.
In addition, for details on user program mode, refer also to and 19-35 in section 19.17, On-Board Programming
Modes.
3. In ROMless version, only modes 4 and 5 are available.
19.4 PROM Mode (H8S/2357 ZTAT)
19.4.1 PROM Mode Setting
The PROM version of the H8S/2357 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 120/128-pin to 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/2357 does not support page programming.
Table 19-4 shows how PROM mode is selected.
