program is changed after production/shipment of the target system. A boot swap function that rewrites the entire flash
memory area safely is also supported. In addition, interrupt servicing is supported during self programming, so that the
flash memory can be rewritten under various conditions, such as while communicating with an external device.

Self programming
The internal flash memory of the V850ES/JG3 can be rewritten by using the rewrite function of the dedicated flash
In addition, a security function that prohibits rewriting the user program written to the internal flash memory is also
The rewrite function using the user program (self programming) is ideal for an application where it is assumed that the
Remark
Rewrite Method
The FA series is a product of Naito Densei Machida Mfg. Co., Ltd.
Flash memory can be rewritten after the device is mounted on the
target system, by using a dedicated flash programmer.
Flash memory can be rewritten before the device is mounted on the
target system, by using a dedicated flash programmer and a dedicated
program adapter board (FA series).
Flash memory can be rewritten by executing a user program that has
been written to the flash memory in advance by means of off-board/on-
board programming. (During self-programming, instructions cannot be
fetched from or data access cannot be made to the internal flash
memory area. Therefore, the rewrite program must be transferred to
the internal RAM or external memory in advance.)
