Connecting the Atmel-ICE

3.1 Connecting to AVR
The Atmel-ICE is equipped with two 50-mil 10-pin JTAG connectors. Both connectors are directly electrically
connected, but conform to two different pinouts; the AVR JTAG header and the Arm Cortex Debug header. The
connector should be selected based on the pinout of the target board, and not the target MCU type - for example, a
SAM device mounted in an AVR STK600 stack should use the AVR header.
Various cabling and adapters are available in the different Atmel-ICE kits. An overview of connection options is
shown.

The red wire marks pin 1 of the 10-pin 50-mil connector. Pin 1 of the 6-pin 100-mil connector is placed to the right of
the keying when the connector is seen from the cable. Pin 1 of each connector on the adapter is marked with a white
dot. The figure below shows the pinout of the debug cable. The connector marked A plugs into the debugger while
the B side plugs into the target board.
