WF_XXX Internal Pin Aliases

These are FPGA chip pins that are wired directly to certain peripherals. For example, the LED is always wired to FPGA pin 31. These FPGA pins are not the same as the external physical PCB pins!

If you are using an external toolchain (IceStorm or iCECube), you might want to set these in your pinmap.pcf.
