i dont understand, before trying to implement it, i like to look at the builtin chips functioning. But it only accepts 0 or 1, so i cant choose between all four 16 bit buses..  what am i missing?  

as for the implementation, is it possible with 2 mux16's and one mux ? the mux to choose between the two mux16s?  i haven;t thought about it much yet as i want to make sure i understand how the chip is supposed to function first

Even more confusing, i just ran the tst file against it and it failed?!
