Programming and Debug Ports
For programming and/or debugging the SAM D20 the device should be connected using the Serial Wire Debug, SWD,
interface. Currently the SWD interface is supported by several Atmel and third party programmers and debuggers, like
the SAM-ICE, JTAGICE3 or SAM D20 Xplained Pro (SAM D20 evaluation kit) Embedded Debugger.

Refer to the SAM-ICE, JTAGICE3 or SAM D20 Xplained Pro user guides for details on debugging and programming
connections and options. For connecting to any other programming or debugging tool, refer to that specific programmer
or debugger’s user guide.

The SAM D20 Xplained Pro evaluation board for the SAM D20 supports programming and debugging through the
onboard embedded debugger so no external programmer or debugger is needed.
