Programming Headers

The XMEGA can be programmed and debugged by connecting an external programming/debugging tool to the PDI header shown in Figure 1.

The gray XMEGA PDI adapter must be used on the Atmel AVR JTAGICE mkII probe when connecting to the XMEGA-E5 Xplained board.

The green standoff adaptor nr.3 (ref.A08-0254) has to be used on the Atmel AVR ONE! probe when connecting to the XMEGA-E5 Xplained board.
