If an IO pin is routed to a peripheral signal through the GPIO matrix, the signal ID printed in the dump information is defined in the :component_file:`soc/{IDF_TARGET_PATH_NAME}/include/soc/gpio_sig_map.h` header file. The word ``**RESERVED**`` indicates the IO is occupied by either SPI flash or PSRAM. It is strongly not recommended to reconfigure them for other application purposes.

Do not rely on the default configurations values in the Technical Reference Manual, because it may be changed in the bootloader or application startup code before app_main.

Current GPIOs are for {IDF_TARGET_NAME} beta3 version. {IDF_TARGET_NAME} MP version would have 2 more available IOs, and some pin functions are changed. The {IDF_TARGET_NAME} MP version will be updated later.
The {IDF_TARGET_NAME} chip features 27 physical GPIO pins (GPIO0 ~ GPIO26). Each pin can be used as a general-purpose I/O, or to be connected to an internal peripheral signal. Through GPIO matrix and IO MUX, peripheral input signals can be from any IO pins, and peripheral output signals can be routed to any IO pins. Together these modules provide highly configurable I/O. For more details, see *{IDF_TARGET_NAME} Technical Reference Manual* > *IO MUX and GPIO Matrix (GPIO, IO_MUX)* [`PDF <{IDF_TARGET_TRM_EN_URL}#iomuxgpio>`__].
The {IDF_TARGET_NAME} chip features 29 physical GPIO pins (GPIO0 ~ GPIO28). Each pin can be used as a general-purpose I/O, or to be connected to an internal peripheral signal.

- Strapping pin: GPIO2, GPIO3, GPIO6, and GPIO7 are strapping pins. For more information, please refer to `datasheet <{IDF_TARGET_DATASHEET_EN_URL}>`__.
- SPI0/1: GPIO18 ~ GPIO24 are usually used for SPI flash and not recommended for other uses.
- USB-JTAG: GPIO25 and GPIO26 are used by USB-JTAG by default. If they are reconfigured to operate as normal GPIOs, USB-JTAG functionality will be disabled.
