30.1.1 Programming Environment
The environment required for writing a program to the flash memory of the RL78/F13 or RL78/F14 is illustrated below.
Figure 30-1. Environment for Writing Program to Flash Memory
Notes 1. 64, 80, 100-pin products only.
2. 100-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/F13 or RL78/F14, the TOOL0 pin is used
for manipulation such as writing and erasing via a dedicated single-line UART.
30.1.2 Communication Mode
Communication between the dedicated flash memory programmer and the RL78/F13 or RL78/F14 is established by serial
communication using the TOOL0 pin via a dedicated single-line UART of the RL78/F13 or RL78/F14.
Transfer rate: 1 M, 500 k, 250 k, 115.2 kbps

Notes 1. When using E1 on-chip debugging emulator.
2. When using PG-FP5 or FL-PR5.
3. 64, 80, 100-pin products only.
4. 100-pin products only.
5. Connect REGC pin to ground via a capacitor (0.47 to 1
 F).
