Preliminary Data Sheet
6. PROGRAMMING FLASH MEMORY
The flash memory can be written with the
μ
PD78F4216 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.
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 V
PP
pulses shown in Table 6-1.
