SSI (Synchronous Serial Interface)

The Synchronous Serial Interface (SSI) protocol has four kinds of signals: Serial Clock (SCK), Transmit Data, Receive Data, and Transmit/Receive Frame Sync (FS). SSI supports Normal or Network mode, independent of whether the transmitter and receiver are synchronous or asynchronous.

Wrong Mode/Line Of Data settings misread frames. For channel-prefix differences, see Settings.
