25.1.1 Programming Environment
The environment required for writing a program to the flash memory of the RL78/G13 is illustrated below.

Note 64-pin, 80-pin, 100-pin and 128-pin products only.
A host machine that controls the dedicated flash memory programmer is necessary.
To interface between the dedicated flash memory programmer and the RL78/G13, the TOOL0 pin is used for
manipulation such as writing and erasing via a dedicated single-line UART. To write the flash memory off-board, a
dedicated program adapter (FA series) is necessary.
25.1.2 Communication Mode
Communication between the dedicated flash memory programmer and the RL78/G13 is established by serial
communication using the TOOL0 pin via a dedicated single-line UART of the RL78/G13.
Transfer rate: 1 M, 500 k, 250 k, 115.2 kbps
