USB OTG full speed (FS) characteristics
This interface is present in both the USB OTG HS and USB OTG FS controllers.
Note:
When VBUS sensing feature is enabled, PA9 and PB13 should be left at their default state
(floating input), not as alternate function. A typical 200 µA current consumption of the
sensing block (current to voltage conversion to determine the different sessions) can be
observed on PA9 and PB13 when the feature is enabled.
