31.4 Rewriting by Dedicated Flash Programmer
The flash memory can be rewritten by using a dedicated flash programmer after the V850ES/JG3-H and V850ES/JH3-
H are mounted on the target system (on-board programming). The flash memory can also be rewritten before the device
is mounted on the target system (off-board programming) by using a dedicated program adapter (FA series).
31.4.1 Programming environment
The following shows the environment required for writing programs to the flash memory of the V850ES/JG3-H and
V850ES/JH3-H.

Note Connect the FLMD1 pin to the flash programmer or connect to GND via a pull-down resistor on the board.
A host machine is required for controlling the dedicated flash programmer.
UARTC0, CSIF0, or CSIF3 is used for the interface between the dedicated flash programmer and the V850ES/JG3-H
and V850ES/JH3-H to perform writing, erasing, etc. A dedicated program adapter (FA series) required for off-board
writing.
Remark The FA series is a product of Naito Densei Machida Mfg. Co., Ltd.
