Device
Some VREF pins are on INPUT pins. See pinout tables for details.
All devices have 24 possible global clock and right- and left-half side clock inputs. The right-half and bottom-edge clock pins have shared
functionality in some FPGA configuration modes. Consequently, some clock pins are counted in the DUAL column. 4 GCLK pins, including
2 DUAL pins, are on INPUT pins.
