3.3.1 Target Connection Pinout

The programming connector pin functions are different for various devices and interfaces. Refer to the following pinout tables for debug and data stream interfaces.
Note: Refer to the data sheet for the device you are using as well as the application notes for the specific interface for additional information and diagrams.

  1. Use of a 6-pin header will result in the loss of functions on Pins 7 and 8 affecting EJTAG, JTAG, SWD and ISP.
  2. SWO is used for trace. SWDIO is used for debug.
  3. dW = debugWIRE
  4. Pin may be used for High-Voltage Pulse reactivation of UPDI function depending on device. See device data sheet for details.
  5. These are example target connectors that are assumed similar to the debugger unit (SIL).

  1. Use of an 8-pin connector is required for data streaming. A 6-pin connector will result in the loss of functions on Pins 7 and 8.
  2. RX and TX pins need to move to accommodate wiring for other devices.
  3. This is an example target connector that is assumed similar to the debugger unit (SIL).
