Using PFI Terminals as Static Digital Inputs and Outputs
When a terminal is used as a static digital input or output, it is called P0.x
or P1.x. On the I/O connector, each terminal is labeled PFI x/P0.x or
PFI x/P1.x.
Connecting PFI Input Signals
All PFI input connections are referenced to D GND. Figure 8-3 shows this
reference, and how to connect an external PFI 0 source and an external
PFI 2 source to two PFI terminals.
