     Additionally, IOs that are powered by the VDD3P3_RTC power domain can be used to wake up the chip from Deep-sleep. The wakeup pin and wakeup trigger level can be configured by calling :cpp:func:`esp_deep_sleep_enable_gpio_wakeup`. The function will enable the Deep-sleep wakeup for the selected pin.
