3. Flash memory initialization
1. Initial state
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.
The flash memory is erased at shipment.
The following describes how to write over
an old-version application program or data in
the flash memory. The user should prepare
the programming control program and
new application program beforehand in the host.

4. Writing new application program
<This LSI>
<This LSI>
When boot mode is entered, the boot program in
this LSI (originally incorporated in the chip) is started
and SCI communication is checked. Then 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 via SCI communication is executed,
and the new application program in the host is written
into the flash memory.
