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.
Use the pinout shown in the figure below when designing an application PCB with an AVR
with the TPI interface included.Figure 2-3. TPI Header Pinout
Direct Connection to a Standard 6-pin 100-mil TPI Header
Use the included 100-mil 6-pin flat cable to connect directly to a board supporting the
TPI header type. Note the pin-1 marking on the cable, and ensure to line it up with the
pin-1 marking on the AVR Programming Adapter.
