Note to
(1)
The IOEs are located in I/O blocks around the periphery of the Cyclone II
device. There are up to five IOEs per row I/O block and up to four IOEs
per column I/O block (column I/O blocks span two columns). The row
I/O blocks drive row, column (only C4 interconnects), or direct link
interconnects. The column I/O blocks drive column interconnects.

There are two paths available for combinational or registered inputs to the logic
array. Each path contains a unique programmable delay chain.
