The GPIO output before initialization

[pass3master]

We are developing a device using the STM32H743.
We are setting up the GPIO during initialization, but I am wondering about something.
What is the GPIO output before initialization? Is it high impedance?
Or does it change depending on the circuit connected to the STM32H743?

Hello,

After reset it's analog input:

 

After reset the output is normally set to 0:

If you need to set it at a specific value on the initialization stage, set the value of the pin on ODR or BSRR register then configure the GPIO as output.

Thank you for your answer. I see, analog input!
Is it floating as an electric potential?

Sorry I didn't understand your last question.

After reset it's set to Analog input and it's in high impedance state (from RM0433):
