The Configuration Problem Solver

Data shifted backwards.

    Check to see if the data is backwards by capturing the first two bytes of the Header on the DOUT pin. If the configuration data is being accessed in byte words and shifted serially into the FPGA then shifting in the wrong direction would result in observing <0000 0100> instead of <0010 0000> on DOUT.
