Thanks for Mark's forward. Hi Jean-Michel, Yes, SWxOMODE can be set as 1 to active sleep mode if PWRON turn-off event occurs. And the voltage of sleep mode can be set in other register SWxOFF. But by default, SWxOMODE is 0 which means all SW will be turned off while PWRON go form 1 to 0. For your issue, I hope you check the hardware design, and measure PWRON pin to see whether it has been pulled low once your push reset key.
