I am using PA14 as a GPIO output pin.
When, I am trying to make it low, it is not going till 0V, but to 2.0V.
At high, the voltage is 3.3V but at low, voltage is 2.0V instead of 0V..
But, with the same configurations, I am able to make other GPIOs to go till 0V.
In the specs also, I am not able to get anything which specify this behavior wrt PA14.
Is there something I am missing here?
