3.3.2 Target Connection Pinouts

The programming connector pin functions are different for various devices and interfaces. Refer to the following pinout tables for debug and data stream interfaces. Legacy 6-pin RJ-11 cable can also be used, however target interfaces which use pins 1 (TMS/SWDIO) and 8 (TDI/MOSI) can not be programmed or debugged.
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. Black (8-pin) cable must be used for EJTAG, JTAG, SWD and ISP.
  2. SWO is used for trace. SWDIO is for debug.
  3. Pin may be used for High-Voltage Pulse reactivation of UPDI function depending on device. See device data sheet for details.
  4. These are example target connectors that are assumed similar to the debug unit (modular).

  1. RX pin moved because of wiring for other devices.
  2. These are example target connectors that are assumed similar to the debug unit (modular).
Note: For 6-pin RJ11 into 8-pin RJ45 socket, pins 1 and 8 are lost.
