INTRODUCTION
PI7C9X110 is a PCIe-to-PCI/PCI-X bridge. PI7C9X110 is compliant with the PCI Express Base Specification,
Revision 1.0a, the PCI Express Card Electromechanical Specification, Revision 1.0a, the PCI Local Bus
Specification, Revision 3.0 and PCI Express to PCI/PCI-X Bridge Specification, Revision 1.0. PI7C9X110
supports transparent and non-transparent mode of operations. Also, PI7C9X110B supports forward and reverse
bridging. In forward bridge mode, PI7C9X110 has an x1 PCI Express upstream port and a 32-bit PCI/PCI-X
downstream port. The 32-bit PCI downstream port is 66MHz capable (see figure 1-1). In reverse bridge mode,
PI7C9X110 has a 32-bit PCI upstream port and an x1 PCI Express downstream port. PI7C9X110 configuration
registers are backward compatible with existing PCI bridge software and firmware. No modification of PCI bridge
software and firmware is needed for the original operation.
