38.7.2 10-pin JTAGICE3 Compatible Serial Wire Debug Interface
The JTAGICE3 debugger and programmer does not support the Cortex Debug Connector (10-pin) directly, hence a
special pinout is needed to directly connect the SAM D21 to the JTAGICE3, alternatively one can use the JTAGICE3
squid cable and manually match the signals between the JTAGICE3 and SAM D21.
