+ * @brief   Exchanges one frame using a polled wait.
+ * @details This synchronous function exchanges one frame using a polled
+ *          synchronization method. This function is useful when exchanging
+ *          small amount of data on high speed channels, usually in this
+ *          situation is much more efficient just wait for completion using
+ *          polling than suspending the thread waiting for an interrupt.
+ *
+ * @param[in] spip      pointer to the @p SPIDriver object
+ * @param[in] frame     the data frame to send over the SPI bus
+ * @return              The received data frame from the SPI bus.
