6. PROGRAMMING FLASH MEMORY
connect a dedicated flash programmer (Flashpro III (part number: FL-PR3, PG-FP3) to the host machine and target
system.

The flash memory can be written with the µ PD78F4218AY mounted on the target board (on-board). To do so,
Writing to flash memory can also be performed using flash memory writing adapter connected to Flashpro III.
Remark FL-PR3 is a product of Naito Densei Machida Mfg. Co., Ltd.
To write the flash memory, use Flashpro III by serial communication. Select a serial communication mode from
