6.4 Connecting the Serial Writer
The built-in Flash memory (user ROM area) in R8C/34K Group MCUs can be re-programmed with a computer or
MCU (serial writer) that has a clock-asynchronous serial transmission (UART 0ch).
The board is equipped with an RS-232C transceiver IC, which is connected to the MCU UART0. UART transmission
between the MCU and the serial writer is carried out through the D-sub9 pin male connector (CN5) as shown in
