What is the state of the GPIO pins during startup of the nRF52832?

Are the GPIO pins in disconnected state during the startup until they are configured by the Firmware? If not what is the state of the GPIO pins during startup?

Hi Ronny,

Yes, except for wake up reset from SystemOFF mode, when starting up the GPIO pin will be in input mode, but input buffer is disconnected. So basically it's a floating pin with high impedance.

If waking up from SystemOFF the GPIO pins will keep the previous configured state.
