But if I read it manually, then it works properly and correctly returns the actual value of the pin state. This is the relevant code: // Configure PA15 pin as input floating. Pull Down because we want to detect a high level.

The voltage level of the floating pin is unclear and cannot be predicted. Also, when a high impedance pin is not led either by pull-up or pull-down circuits, then it is also called a floating pin.

Webb15 dec. 2015 · This gives us a hint that reading output pin state is probably supported by the hardware itself but we can't be sure since it may be cached by the driver, for example. Lets check documentation: The pin level registers return the actual value of the pin. And it doesn't mention that it has to be set to OUTPUT. Experimentation seems to confirm this.
