I/O Blocks  
The IOEs are located in I/O blocks around the periphery of the MAX II device. There  
are up to seven IOEs per row I/O block (5 maximum in the EPM240 device) and up to  
four IOEs per column I/O block. Each column or row I/O block interfaces with its  
adjacent LAB and MultiTrack interconnect to distribute signals throughout the device.  
The row I/O blocks drive row, column, or DirectLink interconnects. The column I/O  
blocks drive column interconnects.
