... SMBus interface is provided according to SMBus specification. Through the Serial Data Interface, various device functions such as individual clock output buffers, can be individually enabled or disabled. CY28322-2 supports both block read and block write operations. The registers associated with the Serial Data Interface initialize to their default setting upon power-up, and therefore use of this interface is optional ...
