GPIO pin state during reset

[Sahar]

Hi,

What is the GPIO pin state during reset, and during startup ? I have seen that it is a high impedance floating input. How much is the value of this impedance? Can I guarantee to drive it at 0V during reset mode bu connecting a pull-down resistor?  I need to know the impedance value to choose the pull-down resistor.

Thank you in advance for your reply

Correct.

It's >>1Mohm, see this and this.
