2.4.3.2. Power, Ready LED
System Ready (RDY): Indicates that the system is operating normally. (Normal: LED blinks)
Power (PWR): Indicates that the 5 V power is being supplied. (Supplying power: Red LED ON)
2.4.3.3. Debug Port LED
DTXD (Debug Port Transmit Dta LED) : Shows transmission status of the Debug Port.
DRXD (Debug Port Receive Data LED) : Shows reception status of the Debug Port.
