6. PROGRAMMING FLASH MEMORY
The flash memory can be written with the µPD78F4218AY mounted on the target board (on-board). To do so,
connect a dedicated flash programmer (Flashpro II (part number: FL-PR2), Flashpro III (part number: FL-PR3, PG-
FP3) to the host machine and target system.
Writing to flash memory can also be performed using flash memory writing adapter connected to Flashpro II or
Flashpro III.
Remark FL-PR2 and FL-PR3 are products of Naito Densei Machida Mfg. Co., Ltd.
6.1 Selecting Communication Mode
To write the flash memory, use Flashpro II and Flashpro III by serial communication. Select a serial
communication mode from those listed in Table 6-1 in the format shown in Figure 6-1. Each communication mode is
selected by the number of VPP pulses shown in Table 6-1.
