GPIO value after wake up from GPIO

Hi everyone,

I'm currently working on a nrf52832 board and i got an issue on Gpio config after a reset.

I configure a gpio with a register value of 4, low level, output pin and clear it before calling sd_power_system_off();

I wake up with a GPIO pin, the reset value is 0x00010000 (read from RESETREAS) and according to the documentation such a reset shoud maintain register value and Gpio configuration.

But after the reset all my gpio are clear and their register value is 3 after a burst peak. In my case that causes a wakeup on my gps ...

Has anyone a clue about this issue ?
