Flexible High Speed I/O
Flexible Input/Output (I/O) is a technology that allows some of the PCH High Speed I/O (HSIO) lanes to be configured for connection to 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 PCH HSIO interfaces to better meet the I/O needs of their system.

The figure below shows the High Speed I/O (HSIO) lane multiplexing:
The 9 Flexible HSIO Lanes [11:8,6,3:0] supports the following configurations:
- Up to nine PCIe* Lanes
- Up to four USB 3.2 Gen 1x1/2x1 Lanes
- Up to two SATA Lanes
- Supports two Lane 1x2 Universal Flash Storage (UFS)
- For unused USB 3.2/PCIe* Combo Lanes, the unused lanes must be statically assigned to PCIe* or USB 3.2 via the USB 3.2/PCIe* Combo Port Soft Straps through the Intel Flash Image Tool (FIT) tool.
