STM32L476G Discovery Board VBUS Voltage on PC11

[FHopp.1]

Hello,

I have an question concerning the VBUS Pin which is connected to the STM32L476G Discovery (PIN PC11) directly. Why isn't 5V an problem for the PC11 pin? I thougt 5V would cause overvoltage?

It's a 5Volt tolerant pin, of Ft type, see STM32L476xx pin definitions table in the 'L476 datasheet.

Note, that it's connected also to PA9 through SB24 - PA9 is the "native" OTG VBUS input.
