- SPI0/1: GPIO12-17 are usually used for SPI flash and not recommended for other uses.
- RTC: GPIO0-5 can be used when in Deep-sleep mode.
- RTC: GPIO0-5 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>`.
