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
