Figure 1.116. Serial Sound Interface architecture
Data transmission format
The transmitter/receiver must change channels on every WS transition. If the number of SCKs within a WS high/low
period exceeds the channel width (set by the user via mode bits), the transmitter continues to transmit '0's, while the
receiver will stop receiving data until the next WS edge. However, if the number of SCKs falls short, both the transmitter
and the receiver will immediately switch to the next channel transmit and receive, respectively. The Serial Sound
Interface architecture is shown in Figure 1.116.
