The flash memory is in the erased state when the
device is shipped. The description here applies to
the case where the old program version or data
is being rewritten. The user should prepare the
programming control program and new
application program beforehand in the host.
The erase program in the boot program area (in
RAM) is executed, and the flash memory is
initialized (to H'FF). In boot mode, entire flash
memory erasure is performed, without regard to
blocks.

When boot mode is entered, the boot program in
the H8/3067 Group chip (originally incorporated
in the chip) is started, an SCI communication
check is carried out, and the boot program
required for flash memory erasing is
automatically transferred to the RAM boot
program area.
The programming control program transferred
from the host to RAM by SCI communication is
executed, and the new application program in the
host is written into the flash memory.
