4.4.8 Connecting to a UPDI Target
The recommended pinout for the 6-pin UPDI connector is shown in
Connection to a 6-pin 100-mil UPDI Header
Use the 6-pin 100-mil tap on the flat cable (included in some kits) to connect to a standard 100-mil UPDI header.
Connection to a 6-pin 50-mil UPDI Header
Use the adapter board (included in some kits) to connect to a standard 50-mil UPDI header.
Connection to a Custom 100-mil Header
The 10-pin mini-squid cable should be used to connect between the Power Debugger AVR connector port and the
target board. Three connections are required, as described in the table below.

4.4.9 TPI Physical Interface
TPI is a programming-only interface for some tinyAVR devices. It is not a debugging interface, and these devices do
not have OCD capability. When designing an application PCB which includes an AVR with the TPI interface, the
pinout shown in the figure below should be used.

4.4.10 Connecting to a TPI Target
The recommended pinout for the 6-pin TPI connector is shown in
Connection to a 6-pin 100-mil TPI Header
Use the 6-pin 100-mil tap on the flat cable (included in some kits) to connect to a standard 100-mil TPI header.
Connection to a 6-pin 50-mil TPI Header
Use the adapter board (included in some kits) to connect to a standard 50-mil TPI header.
Connection to a Custom 100-mil Header
The 10-pin mini-squid cable should be used to connect between the Power Debugger AVR connector port and the
target board. Six connections are required, as described in the table below.
