			Serial Peripheral Interface

			The SPI enabled device typically has the following pins:
			* SS: A line indicating slave device selection
			* MISO and MOSI (Master In Slave Out): A line for sending serial data to the Master device
			* SCK/SCLK (Serial Clock): A clock signal generated by the Master device to synchronize data transmission, so the slave device knows when to read the input.
			* RESET: A line for restarting the transmission process.
