Boot program
(old version)
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.
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.

2. Programming control program transfer
4. Writing new application program
When boot mode is entered, the boot program in
this LSI (originally incorporated in the chip) is
started and the programming control program in
the host is transferred to RAM via SCI or USB
communication. 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 is executed, and the new
application program in the host is written into the
flash memory.
