Seven General Purpose Input/Output (GPIO) pins, labeled GPIO 0 to 6, are available to allow for application specific functions. Each GPIO pin can be programmed as an input (the value of the pin can be read by the host or internal processor) or as an output (the output values can be programmed by the host or internal processor), where the default mode after power-up is input.

Note: Usage of the GPIO functionality is not supported by the WINC15x0 FW. The datasheet will be updated once the support for this feature is added.
