27.4 Rewriting by Dedicated Flash Programmer
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).
27.4.1 Programming environment

The flash memory can be rewritten by using a dedicated flash programmer after the V850ES/JJ3 is mounted on the
The following shows the environment required for writing programs to the flash memory of the V850ES/JJ3.
A host machine is required for controlling the dedicated flash programmer.
UARTA0, CSIB0, or CSIB3 is used for the interface between the dedicated flash programmer and the V850ES/JJ3 to
• FA-70F3368GJ-UEN-RX (already wired)
• FA-144GJ-UEN-A (not wired: Wiring is required.)
Remark
Note Connect the FLMD1 pin to the flash programmer or connect to a GND via a pull-down resistor on the board.
The FA series is a product of Naito Densei Machida Mfg. Co., Ltd.
