(8) Writing in the user ROM area

If power is lost while rewriting blocks that contain the flash rewrite program with the CPU rewrite mode,

those blocks may not be correctly rewritten and it is possible that the flash memory can no longer be

rewritten after that. Therefore, it is recommended to use the standard serial I/O mode or parallel I/O

mode to rewrite these blocks.

(9) Using the lock bit

To use the CPU rewrite mode, use a boot program that can set and cancel the lock command.
