SIGN INSerial peripheral interface (SPI) is the full duplex synchronous serial interface consisting of four signals: SCLK (serial clock), COTI (controller out, target in), CITO (controller in, target out) and TS (target select) used for short-distance, high-speed communications. The SPI bus operates with a single controller device and one or more target devices with data rate ranges from 5 to 20 Mbit/s.
