Hello,

Yes all the unused Pins should be in analog state and you can keep the used Pins in the mode you have already configured.

Hello,

You need to put the GPIOs in analog state.

@Mohamed Aymen HZAMI You mean all un active pins should be in analog state? If I already put some pins in output high/low or Pull-up/ pull-down in idle mode, what is the state for those pins in standby mode? Are they going to have high impedance or would they preserve the orginal configurations in order to not have power leakage?
