PCI interface
The DN9002K10PCI can be installed in a PCI slot, either 32 or 64 bits, 33 or 66Mhz. It can
also be used in a PCI-X slot. (Although the entire bus will only run at 66Mhz in this
configuration).
A QuickLogic QL5064 bridge provides PCI on the DN9002K10PCI. This device has a PCI
controller on the front end, and an FPGA on the back end. The Dini Group has pre-
programmed this device to provide a simple FIFO interface.
