24.2 Writing with Flash memory programmer
Data can be written to the flash memory on-board or off-board, by using a dedicated flash memory programmer.
(1) On-board programming
The contents of the flash memory can be rewritten after the 78K0/LC3 has been mounted on the target system.
The connectors that connect the dedicated flash memory 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 78K0/LC3 is
mounted on the target system.
Remark The FA series is a product of Naito Densei Machida Mfg. Co., Ltd.

Notes 1. Only the X1 clock (fX) or external main system clock (fEXCLK) can be used when UART6 is used. When
using the clock output of the dedicated flash memory programmer, pin connection varies depending on the
type of the dedicated flash memory programmer used.
• PG-FP4, FL-PR4: Connect CLK of the programmer to EXCLK/X2/P122 (pin 10).
• PG-FPL3, FP-LITE3: Connect CLK of the programmer to X1/P121 (pin 11), and connect its inverted
signal to X2/EXCLK/P122 (pin 10).
