[sdiy] Avnet Spartan-3A Dev Board - USB-UART Bridge Info

[Scott Gravenhorst]

Anyone who has this board - a note about the USB-UART Bridge (which is useful for getting information to/from a PC), the pin information in the user guide PDF is wrong, there are no such pins on this particular FPGA.  The schematic shows the correct pins, but because they are labeled from the PSoC perspective, they appear backwards from the FPGA perspective.  I.e., the Rx pin is really the transmit data pin from the FPGA to the UART.
