TM4C1290NCZAD: Reading from a GPIO output pin

Hi,

from a new colleague I got a question about how he can read from a GPIO pin when it is configured as an output. It makes sense to be able to do that from an open drain with a pull up, but it seems that he can only read from an internal register and not the pin.
