:cpp:func:`esp_sleep_enable_ext1_wakeup` function can be used to enable this wakeup source for general ext1 wakeup.
:cpp:func:`esp_sleep_enable_ext1_wakeup_io` function can be used to append ext1 wakeup IO and set corresponding wakeup level.

Besides the above mentioned general ext1 wakeup, the RTC controller also contains a more powerful logic to trigger wakeup using multiple RTC GPIOs with a customized RTC IO wakeup level bitmap. This can be configured with :cpp:func`esp_sleep_enable_ext1_wakeup_with_level_mask`.
The RTC controller also supports triggering wakeup, allowing configurable IO to use different wakeup levels simultaneously. This can be configured with :cpp:func`esp_sleep_enable_ext1_wakeup_io`.
