Altera EP910 devices can implement up to 450 usable gates of SSI and MSI
logic functions. EP910 devices have 24 macrocells, 12 dedicated input
pins, 24 I/O pins, and 2 global clock pins (see
can access signals from the global bus, which consists of the true and
complement forms of the dedicated inputs and the true and complement
forms of either the output of the macrocell or the I/O input. The CLK1 and
CLK2 signals are the dedicated clock inputs for the registers in macrocells
13 through 24 and 1 through 12, respectively.
