Overview

The TI XIO2213BZAY is a PCIe to PCI translation bridge, where the PCI bus interface is internally connected to a 1394b open host controller/link-layer controller with a 3-port 1394b PHY. The PCIe to PCI translation bridge is fully compatible with the PCI Express to PCI/PCI-X Bridge Specification, Revision 1.0. Also, the bridge supports the standard PCI-to-PCI bridge programming model. The 1394b OHCI controller function is fully compatible with IEEE Std 1394b and the latest 1394 Open Host Controller Interface (OHCI) Specification.

Three package terminals are used as inputs to set the default value for three configuration status bits in the self-ID packet. They can be pulled high through a 1-k resistor or hardwired low as a function of the equipment design. The PC0, PC1, and PC2 terminals indicate the default power class status for the node (the need for power from the cable or the ability to supply power to the cable). The contender bit in the PHY register set indicates that the node is a contender either for the isochronous resource manager (IRM) or for the bus manager (BM). On the XIO2213B, this bit can only be set by a write to the PHY register set. If a node is to be a contender for IRM or BM, the node software must set this bit in the PHY register set.
