4.4.9. TPI Physical Interface
TPI is a programming-only interface for some AVR ATtiny 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 Figure 4-13.
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 Atmel-ICE AVR connector port and
the target board. Six connections are required, as described in the table below.
