C1 = Clock (Clk)
C2 = Data
C3 = Chip Select (Cs)
blue results = completely decoded words
grey brackets = start and end of complete frame
red results = Incomplete word that is not completely contained in the acquisition. Change the horizontal
scale, or move the"Time Reference" to get a longer acquisition.
Additionally, you can display and save a "Frame Table" containing decoded data: frame
number, start time of the frame, source (line), data and state of the frame.
