On-Board Programming Modes
Boot mode
1. Initial state
3. Flash memory initialization
The chip
The chip
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.

2. Programming control program transfer
4. Writing new application program
The chip
The chip
When boot mode is entered, the boot program in
the 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.
