STM32F413xG/H Electrical characteristics
174
Note:
When VBUS sensing feature is enabled, PA9 should be left at their default state (floating
input), not as alternate function. A typical 200
µA current consumption of the embedded
sensing block (current to voltage conversion to determine the different sessions) can be
observed on PA9 when the feature is enabled.

Refer to Section 6.3.16: I/O port characteristics for more details on the input/output alternate
function characteristics (CANx_TX and CANx_RX).
