User programming mode
1. Initial state
3. Flash memory initialization
(1) The program that will transfer the on-board
update routine to on-chip RAM should be
written into the flash memory by the user
beforehand. (2) The on-board update routine
should be prepared in the host or in the flash
memory.
The update routine in RAM is executed, and
the flash memory is initialized (to H'FF).
Erasing can be performed in block units, but
not in byte units.

4. Writing new application program
2. On-board update routine transfer
Next, the new application program in the host is
written into the erased flash memory blocks. Do
not write to unerased blocks.
The transfer program in the flash memory is
executed, and the on-board update routine is
transferred to RAM.
