5.3 FSI Frame

The FSI module transmits and receives information in frames. The shortest frame is 16 bits long (without counting the preamble and post amble clock edges). The basic frame structure for 16-bit data is shown in Table 2. Table 3 shows the same for 128-bit data. In the normal mode of transmission, there are four preamble clock edges before the start of the frame and 4 clock edges after the frame. Data is transmitted on both edges of the clock. Each field of the frame (like the Start-of-Frame, Frame type, and so forth) will be transmitted with the most significant bit sent first.
