The CSI2 protocol layer transports virtual channels. Virtual channels are built of frames. A frame can comprise embedded data and image-sensor data. Two contexts are used to send the two types of data (embedded and image-sensor) separately. Each frame is identified by unique mandatory synchronization codes: frame start and frame end. Line start and line end synchronization codes are optional for the transmitter. A set of registers is associated with each context defined by the virtual channel ID and the data type. Figure 8-19 shows a virtual channel.
