RH850 Console

After the target is connected, the MCU prompt displays in the serial console. Use the MCU console to run commands and get information from the MCU.

UART Settings

The serial communication settings for the MCU console are as follows:

• Baud rate: 115,200 bits per second (bps)

• Data: 8-bit, no parity, 1 stop
