Each global clock network has a clock control block to select from a
number of input clock sources (PLL clock outputs, CLK[] pins, DPCLK[]
pins, and internal logic) to drive onto the global clock network.
lists how many PLLs, CLK[] pins, DPCLK[] pins, and global clock
networks are available in each Cyclone II device. CLK[] pins are
dedicated clock pins and DPCLK[] pins are dual-purpose clock pins.
