Remark:
21.4 Programming Environment
The following shows the environment required for writing programs to the flash memory of V850E/RS1.
A host machine is required for controlling the dedicated flash programmer.
UARTA0 or CSIB0 is used for the interface between the dedicated flash programmer and the
V850E/RS1 to manipulate the flash programmer by writing or erasing. To write the flash memory
off-board, a dedicated program adapter (FA series) is necessary.

Off-board programming
The flash memory of the V850E/RS1 can be written before the device is mounted on the target
system, by using a dedicated program adapter (FA series).
