Description for the XIO3130EVM
The Texas Instruments XIO3130 EVM is a functional implementation of a four-port PCIe-to-PCIe switch. The XIO3130 EVM was designed to allow validation of three separate functional modes. In normal mode the EVM is configures as a generic PCI Express switch. In Hot Plug modedownstream ports 1 and 2 are configured as Hot Pluggable slots. In ExpressCard mode all three downstream ports are configured to support the ExpressCard adapter board. The different functional modes will be discussed later in this document.
