CHAPTER 27 FLASH MEMORY
27.3 Communication Mode
Communication between the dedicated flash memory programmer and the 78K0R/Lx3 microcontrollers is established
by serial communication using the TOOL0 pin via a dedicated single-line UART of the 78K0R/Lx3 microcontrollers.
Transfer rate: 115,200 bps to 1,000,000 bps
