3.3.3 SAM MCUs - JTAG/SWD Adapter Board

All SAM devices feature the Serial Wire Debug (SWD) interface for programming and debugging. In addition, some SAM devices feature a JTAG interface with identical functionality. Check the device data sheet for supported interfaces of that device.

An “ICE 4 JTAG Adapter Board” with a 10-pin (top) or 20-pin (bottom) connector is available for legacy target connections.
