- SPI0/1: GPIO15-21 are usually used for SPI flash and not recommended for other uses.

|
|
- USB-Serial-JTAG: GPIO 26 and 27 are used by USB-Serial-JTAG by default. In order to use them as GPIOs, USB-Serial-JTAG will be disabled by the drivers.

- 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.
