* This will append selected IOs to the wakeup IOs, it will not reset previously enabled IOs.
* To reset specific previously enabled IOs, call esp_sleep_clear_ext1_wakeup_io with the io_mask.
* To reset all the enabled IOs, call esp_sleep_clear_ext1_wakeup_io(0).
*
* This function uses external wakeup feature of RTC controller.
* It will work even if RTC peripherals are shut down during sleep.
*
* This feature can monitor any number of pins which are in RTC IOs.
* Once selected pins go into the state given by level_mode argument,
* the chip will be woken up.
*
* @note This function does not modify pin configuration. The pins are
* configured in esp_deep_sleep_start/esp_light_sleep_start,
* immediately before entering sleep mode.
*
* @note Internal pullups and pulldowns don't work when RTC peripherals are
* shut down. In this case, external resistors need to be added.
* Alternatively, RTC peripherals (and pullups/pulldowns) may be
* kept enabled using esp_sleep_pd_config function. If we turn off the
* ``RTC_PERIPH`` domain or certain chips lack the ``RTC_PERIPH`` domain,
* we will use the HOLD feature to maintain the pull-up and pull-down on
* the pins during sleep. HOLD feature will be acted on the pin internally
* before the system entering sleep, and this can further reduce power consumption.

:cpp:func:`esp_sleep_enable_ext1_wakeup` function can be used to enable this wakeup source for general ext1 wakeup.
:cpp:func:`esp_sleep_append_ext1_wakeup` function can be used to append ext1 wakeup IO and set corresponding wakeup level.

.. only:: SOC_PM_SUPPORT_EXT1_WAKEUP_MODE_PER_PIN
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_append_ext1_wakeup`.

除了上述提到的普通 ext1 唤醒之外，当前的 RTC 控制器也包含更强大的逻辑，可以使用多个 RTC GPIO 并根据自定义的 RTC IO 唤醒电平位图来唤醒。这可以通过:cpp:func:`esp_sleep_enable_ext1_wakeup_with_level_mask` 函数来进行配置。
