# NOTE: Follow these instructions when you connect your own circuitry to the XS-40 board:
# 
# 1. Do *NOT* connect your own power supply to any of the FPGA Vcc pins
# 2. Connect your circuit's ground to one or more of the FPGA ground pins
# 3. Do not exceed 5V on FPGA inputs (inputs expect 3.3V, but are 5-volt tolerant)
# 4. Realize that the FPGA is a 3.3V device, so a HIGH level output is 3.3V
# 5. You may use the FPGA Vcc pins (3.3V) to power your own circuit, provided your circuit does not
#      require a large amount of current. 
#
# Ground pins: 12, 21, 31, 43, 52, 64, and 76 (must connect one or more of these to your circuit)
#
# Vcc pins: 2, 11, 22, 33, 42, 54, 63, and 74 (only connect to these pins if you are powering your 
# circuit from the XS-40 board and are not using another power supply!)
