1. Initial state
3. Flash memory initialization
The FWE assessment program that confirms that
user program mode has been entered, and the
program that will transfer the programming/erase
control program from flash memory to on-chip
RAM should be written into the flash memory by
the user beforehand. The programming/erase
control program should be prepared in the host
or in the flash memory.
The programming/erase program 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.

Section 20 Flash Memory (F-ZTAT Version)
When user program mode is entered, user
software confirms this fact, executes transfer
program in the flash memory, and transfers the
programming/erase control program to RAM.
Next, the new application program in the host is
written into the erased flash memory blocks. Do
not write to unerased blocks.
