CHAPTER 24 FLASH MEMORY
24.3 Programming Environment
The environment required for writing a program to the flash memory of the 78K0/LC3 is illustrated below.

78K0/LC3
A host machine that controls the dedicated flash memory programmer is necessary.
To interface between the dedicated flash memory programmer and the 78K0/LC3, UART6 is used for manipulation
such as writing and erasing. To write the flash memory off-board, a dedicated program adapter (FA series) is
necessary.
24.4 Communication Mode
Communication between the dedicated flash memory programmer and the 78K0/LC3 is established by serial
communication via UART6 of the 78K0/LC3.
• UART6
Transfer rate: 115200 bps

Note The above figure illustrates an example of wiring when using the clock output from the PG-FP4 or FL-PR4.
When using the clock output from the PG-FPL3 or FP-LITE3, connect CLK to X1/P121, and connect its
inverted signal to X2/EXCLK/P122.

Caution Only the bottom side pins (pin numbers 23 and 24) correspond to the UART6 pins (RxD6 and
TxD6) when writing by a flash memory programmer. Writing cannot be performed by the top side
pins (pin numbers 48 and 47).
