PCI Connection
The 124-pin PCI connector installed at the bottom-left corner of the board is used for 32-bit PCI. With this PCI con-
nector, PCI IP and proper LatticeXP2 FPGA design, the LatticeXP2 Advanced Evaluation board can be used in a
PCI slot on a PC motherboard. There are two sides to the PCI connector, component side (J11) and solder side
(J56). Refer to Tables 28 and 29 for a description of the PCI connections where the I/O direction is referenced to
the LatticeXP2 Advanced Evaluation Board.
