The H8/3052BF 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 writer that supports the Renesas Technology microcomputer device type
with 512-kbyte on-chip flash memory.
18.10.1 Socket Adapters and Memory Map
In PROM mode using a PROM writer, 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 writer. The socket adapter product codes are given in table
18.12. In the H8/3052BF PROM mode, only the socket adapters shown in this table should be
used.

vector table is needed by the overlap RAM.
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 P1 or E1 bit in FLMCR1, or the P2 or E2 bit in FLMCR2,
is set to 1, even while the emulation function is being used. For details, see section
18.11, Flash Memory Programming and Erasing Precautions.
in FLMCR1, or the P2 bit or E2 bit in FLMCR2, is set to 1, in the same way as with
normal programming and erasing. The P1 and E1 bits and the P2 and E2 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 SWE1 bit in FLMCR1 is 0, or the
SWE2 bit in FLMCR2 is 0, while a high level is being input to the FWE pin.
