Expand description

@brief RTC GPIO set direction in deep sleep mode or disable sleep status (default). In some application scenarios, IO needs to have another states during deep sleep.

NOTE: ESP32 supports INPUT_ONLY mode. The rest targets support INPUT_ONLY, OUTPUT_ONLY, INPUT_OUTPUT mode.

@param gpio_num GPIO number (e.g. GPIO_NUM_12) @param mode GPIO direction

@return - ESP_OK Success - ESP_ERR_INVALID_ARG GPIO is not an RTC IO
