| · The signals connected to CN1 - CN4 can all be user by the user.· Clock input can be freely selected from among input from 
              the base system (33MHz), OSC on the module (50MHz), SMA input, input 
              from another module (CN1 - CN4), etc.
 · Clock can be provided non-skewed to the SDRAM, FPGA by 
              the clock driver on the functional module.
 · Input and output to the base system (PCI, LED, SW, etc.) 
              can all be used.
 · LEDs are provided for debugging.
