Flexible I/O Lane Selection

HSIO lane configuration and type is statically selected by soft straps, which are managed through the Platform Flash Image Tool, available as part of Intel® CSME releases. Refer to the SPI Programming Guide documentation for details on how to configure the Flexible I/O lanes via soft straps.

Note:It is the responsibility of the platform designers to configure the lane muxing and soft straps correctly without any conflict. The hardware behavior is undefined if this scenario ever happens.

PCIe*/SATA Lane Selection

In addition to static configuration via soft straps, Flexible I/O Lanes that have PCIe*/SATA multiplexing can be configured via SATAXPCIE signaling to support implementation like SATA Express or mSATA, where the port configuration is selected by the type of the add-in card that is used. Refer to the Platform SPI Programming Guide for more details on how to configure SATAXPCIE for SATA/PCIe* lane selection.
