The user is free to use the 75 MHz clock inputs for any purpose in addition to clocking the
QL5064_interface_module module.
Note that the 64-bit, bi-directional, 75 MHz interfaces between FPGA A and the QL5064 has
enough bandwidth to fully saturate PCI.
The signals between the QL5064 and the FPGA A are 3.3V, LVCMOS signals.
There is a yellow LED, DS149 indicating activity on the PCI bus. This LED is located near the
PCI edge connector.

Troubleshooting
If under PCI, the board always returns 0xFFFFFFFF this indicates that the Quick Logic 5064
has not been configured by the host system. Usually, this happens a few seconds after the
computer starts up. The host system accesses the QL5064 on the DN9002K10PCI and writes
to registers in the device to tell it what its assigned address ranges are. If these registers are not
set, the QL5064 will not know which bus transactions it should respond to and the bus will
return 0xFFFFFFFF on an error.
One situation that can cause the QL5064 is if the user fails to respond to one or more accesses
to an unused BAR. If you do not wish to use a BAR, you should respond to requests on unused
BARs anyway.

Configuration
The following pins (All FPGAs) are the Select Map data pins, used to configure the FPGAs.
These pins are connected to both Virtex-5 FPGAs. Using these signals for FPGA interconnect
is possible, but may interfere with the configuration circuitry on the DN9002K10PCI.
