- For chip variants with an SiP flash built in, GPIO15 ~ GPIO21 are dedicated to connecting the SiP flash and are not fan-out to the external pins. In addition, GPIO6 ~ GPIO7 are also not fan-out to the external pins. In conclusion, only GPIO0~ GPIO5, GPIO8~ GPIO14, GPIO22~ GPIO27 are available to users.
- For chip variant without SiP flash, apart from the flash IOs mentioned above, GPIO22 is not fan-out to the external pin, thus they're not available to users.
- RTC: GPIO7-14 can be used to wake up the chip from Deep-sleep mode. Other GPIOs can only wake up the chip from Light-sleep mode. For more information, please refer to Section :ref:`Wakeup Sources<api-reference-wakeup-source>`.

If Wi-Fi connections need to be maintained, enable Wi-Fi Modem-sleep mode and automatic Light-sleep feature (see :doc:`Power Management APIs <power_management>`). This will allow the system to wake up from sleep automatically when required by the Wi-Fi driver, thereby maintaining a connection to the AP.
