4. As in on-board programming mode, care is required when applying and releasing FWE to
prevent erroneous programming or erasing. To prevent erroneous programming and erasing
due to program runaway during FWE application, in particular, the watchdog timer should be
set when the P or E bit is set to 1 in FLMCR1, even while the emulation function is being used.
5. When the emulation function is used, NMI input is prohibited when the P bit or E bit is set to 1
in FLMCR1, in the same way as with normal programming and erasing.
The P and E bits are cleared by a reset (including a watchdog timer reset), in standby mode,
when a high level is not being input to the FWE pin, or when the SWE bit in FLMCR1 is 0
while a high level is being input to the FWE pin.

Flash Memory PROM Mode
The H8/3022F has a PROM mode as well as the on-board programming modes for programming
and erasing flash memory. In PROM mode, the on-chip ROM can be freely programmed using a
general-purpose PROM programmer that supports the Hitachi microcomputer device type with
256-kbyte on-chip flash memory (FZTAT256).
15.10.1 Socket Adapters and Memory Map
In PROM mode using a PROM programmer, memory reading (verification) and writing and flash
memory initialization (total erasure) can be performed. For these operations, a special socket
adapter is mounted in the PROM programmer. The socket adapter product codes are given in table
15-13. In the H8/3022F PROM mode, only the socket adapters shown in this table should be used.
