Flexible High Speed I/O

Flexible Input/Output (I/O) is a technology that allows the High Speed I/O (HSIO) lanes to be configured for connection to a Gigabit Ethernet (GbE) Controller, a PCIe* Controller, an Extensible Host Controller Interface (xHCI) USB 3.2 Controller, or an Advanced Host Controller Interface (AHCI) SATA Controller. Flexible I/O enables customers to optimize the allocation of the HSIO interfaces to better meet the I/O needs of their system.

Note:Some Flexible I/O multiplexing capabilities are not available on all SKUs. Refer to Introduction for specific SKU implementation details.
