27.3 Writing with Flash Programmer
Data can be written to the flash memory on-board or off-board, by using a dedicated flash programmer.
(1) On-board programming
The contents of the flash memory can be rewritten after the
μ
PD78F0134 or 78F0138 has been mounted on the
target system. The connectors that connect the dedicated flash programmer must be mounted on the target
system.
(2) Off-board programming
Data can be written to the flash memory with a dedicated program adapter (FA series) before the
μ
PD78F0134 or
78F0138 is mounted on the target system.
Remark
The FA series is a product of Naito Densei Machida Mfg. Co., Ltd.

Notes 1.
When using the clock out of the flash programmer, connect CLK of the programmer to X1, and connect
its inverse signal to X2.
2.
Flashpro III only
Cautions 1. Be sure to connect the REGC pin in either of the following ways.
To GND via a 1
μ
F capacitor
Directly to V
DD
2. When connecting the REGC pin to GND via a 1
μ
F capacitor, the clock cannot be supplied
from the CLK pin of the flash programmer.
Create an oscillator on the board to supply a clock.
