Figure 5-7. SAM-ICE using an Atmel-ICE Adapter

Important: 

If contention with the on-board EDBG occur, power the Xplained Pro board from another input
like the external power header or from the target USB. Physically removing the connection
between the EDBG and the debug header by removing 0Ω resistors, where available, or cutting
the tracks to the EDBG can also be done.
