3.4 Connecting to a PDI Target
The recommended pinout for the 6-pin PDI connector is shown in Figure 4-6, “PDI Header
Pinout” on page 22.
Connection to a 6-pin 100-mil PDI header
Use the 6-pin 100-mil tap on the flat cable (included in some kits) to connect to a standard 100-mil PDI header.
Connection to a 6-pin 50-mil PDI header
Use the adapter board (included in some kits) to connect to a standard 50-mil PDI header.
Connection to a custom 100-mil header
The 10-pin mini-squid cable should be used to connect between the Atmel-ICE AVR connector port and the
target board. Four connections are required, as described in the table below.
Note
There is a difference from the JTAGICE mkII JTAG probe, where PDI_DATA is connected to pin 9.
The Atmel-ICE is compatible with the pinout used by the JTAGICE3, AVR ONE! and AVR Dragon
products.

3.5 Connecting to a debugWIRE Target
The recommended pinout for the 6-pin debugWIRE (SPI) connector is shown in Figure 4-7, “debugWIRE (SPI)
Header Pinout” on page 22.
Connection to a 6-pin 100-mil SPI header
Use the 6-pin 100-mil tap on the flat cable (included in some kits) to connect to a standard 100-mil SPI header.
