title: STMicroelectronics STM32 MPU High-Speed USB PHY

description:
  USB2 PHY block in STM32 is attached to USB 2.0 Host controller and
  USB 2.0 side of DWC3 DRD controller, and provides the USB LS/FS/HS
  connectivity. Both PHYs are the FEMTO-PHY, but their configuration
  bits in the system control register are different for each variant.
