3.3 Connecting to a PDI Target
The pinout for the 6-pin PDI connector is shown in Figure 4-5.
The adapters provided in the kit (A08-0735-B and A08-0735-C) can be used to connect to this pinout in either 50-mil or 100-mil options.
Be sure to use the correct orientation of the 6-pin header when connecting the Atmel JTAGICE3 to the target application PCB. A 'dot' on the adapter board indicates pin 1.
When connecting to a target that does not have the standard 6-pin header, you can use the 10-pin mini-squid cable between the JTAGICE3 target connector and the target board. Four connections are required, and the table below describes where to connect them.
Note: There is a difference from the JTAGICE
mkII JTAG probe, where PDI_DATA is connected to pin 9. The JTAGICE3 is compatible with the
pinout used by the Atmel AVR ONE! and Atmel AVR Dragon™
products.
