Once the IDE chain is connected to the device it blocks the device LED driver. Therefore, the
application can be written in a normal fashion using LED as desired in the final application without
worry of being disconnected from the debug chain. The only limitation is that the LED will not be lit
from the application during the IDE debug session. The user will still observe LED activity, but that
activity is related to the debug chain communicating with the device, not the user application driving
the LED.
