16.3 Programming Environment

The following shows the environment required for writing programs to the flash memory of the V850E/IA1.
Figure 16-1. Environment for Writing Program to Flash Memory
Host machine
A host machine is required for controlling the dedicated flash programmer.
UART0 or CSI0 is used for the interface between the dedicated flash programmer and the V850E/IA1 to perform
writing, erasing, etc. A dedicated program adapter (FA Series) is required for off-board writing. Supply the operating
clock of the V850E/IA1 via the oscillator configured on the V850E/IA1 board using a resonator and a capacitor.

16.4 Communication Mode

(1) UART0
Transfer rate: 4,800 bps to 76,800 bps (LSB first)
