How to properly rewrite the internal flash memory using user boot?

Latest Updated:02/24/2012

Question:

I would like to rewrite the internal flash memory using user boot.
Is it necessary to write a rewrite program for the flash memory in advance using a flash programmer? To which addresses should I write the rewrite program?

Answer:

Yes, it is necessary to write your flash memory rewrite program in advance.
When you allocate the rewrite program from address 10000h in program ROM2, and write the necessary setting for starting in user boot mode to the user boot code area, the user boot function can be used. Refer to the "User Boot Function" section in the Hardware Manual regarding the setting for starting in user boot mode.
