INTRODUCTION
PI7C9X110 is a PCIe-to-PCI 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 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 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.
