Notes to Table 6–8:
(1) User I/O pins are used as inputs or outputs; clock input pins are used as inputs only; clock output pins are used as output only.
(2) For differential pad placement guidelines, refer to “Pad Placement” on page 6–23.
(3) The I/O pin count includes all GPIOs, dedicated clock pins, and dual-purpose configuration pins. Dedicated configuration pins are not included in the pin count.
(4) The true LVDS count includes all LVDS I/O pairs, differential clock input and clock output pins in row I/O banks 1, 2, 5, and 6.
(5) The emulated LVDS count includes all LVDS I/O pairs, differential clock input and clock output pins in column I/O banks 3, 4, 7, and 8.
(6) LVDS input and output buffers are sharing the same p and n pins. One LVDS I/O channel can only be either transmitter or receiver at a time.
