5.2.3 Debug Out
The EK-RA4M3 board can be configured to use the S124 Debug MCU to debug target RA MCU on an
external board.
A yellow indicator, LED5, shows the visual status of the debug interface. When the EK-RA4M3 board is
powered on, and LED5 is blinking, this indicates that the S124 Debug MCU is not connected to a
programming host. When LED5 is on solid, this indicates that the S124 Debug MCU is connected to a
programming interface.
