GPIO Header (P7)

The GPIO header has been design such that when in differential mode, the positive (P) and

negative (N) signals are adjacent on a standard ribbon cable.

Note that the GPIO voltage level is set via hardware.

FCG001: has L12 populated, enabling 2.5V I/O, including LVDS

FCG002: has L13 populated, enabling 3.3V I/O
