| 19 | * The VIM3 on-board MCU can mux the PCIe/USB3.0 shared differential |
| 20 | * lines using a FUSB340TMX USB 3.1 SuperSpeed Data Switch between |
| 21 | * an USB3.0 Type A connector and a M.2 Key M slot. |
| 22 | * The PHY driving these differential lines is shared between |
| 23 | * the USB3.0 controller and the PCIe Controller, thus only |
| 24 | * a single controller can use it. |
| 25 | * If the MCU is configured to mux the PCIe/USB3.0 differential lines |
| 26 | * to the M.2 Key M slot, uncomment the following block to disable |
| 27 | * USB3.0 from the USB Complex and enable the PCIe controller. |
| 28 | * The End User is not expected to uncomment the following except for |
| 29 | * testing purposes, but instead rely on the firmware/bootloader to |
| 30 | * update these nodes accordingly if PCIe mode is selected by the MCU. |
