Boot Mode
1. Initial state
3. Flash memory initialization
Note: Never apply 12 V to the H8/3048F-ONE (single power supply).
The old program version or data remains written
in the flash memory. The user should prepare the
programming control program and new
application program beforehand in the host.
H8/3048F-ONE
The erase program in the boot program area (in
RAM) is executed, and the flash memory is
initialized (to H'FF). In boot mode, total flash
memory erasure is performed, without regard to
blocks.

H8/3048F-ONE
When boot mode is entered, the boot program in
the H8/3048F-ONE (originally incorporated in the
chip) is started and the programming control
program in the host is transferred to RAM via SCI
communication. The boot program required for
flash memory erasing is automatically transferred
to the RAM boot program area.
The programming control program is recognized
if it corresponds to the H8/3048F-ONE.
The programming control program is then
transferred from the host to RAM is executed,
and the new application program in the host is
written into the flash memory.
