I thought it was "Programmable Function Interface". <a href="http://zone.ni.com/reference/en-XX/help/370592G-01/digitizers/pfi_lines/" target="_blank">Brief description</a>.

Programmable Function Interface (PFI).&nbsp;

One of the best resources for learning more
about them is in the manuals of the products that have them.&nbsp; For example, take a look at chapter 8 of the <a href="http://www.ni.com/pdf/manuals/371022k.pdf" target="_blank">M-Series
user manual</a>. &nbsp; It has a great explanation
of what PFI can be used for.
