          +# I2S-dat 

          +

          +An I2S (Interactive Two-Way Serial) interface is a type of serial communication protocol used for transferring data between devices. 

          +

          +It is commonly used in computer networking, as well as in audio processing and digital electronics. 

          +

          +I2S interfaces typically use a combination of fast and slow data transfer rates to make efficient use of communication bandwidth and minimize noise and errors. 

          +

          +One of the key features of I2S interfaces is their ability to support full-duplex communication, which allows for the simultaneous transfer of data in both directions. 

          +

          +This makes I2S a popular choice for high-speed data transfer applications.
