All the timings for the SSI are given for a non-inverted serial clock polarity
(TSCKP/RSCKP = 0) and a non-inverted frame sync (TFSI/RFSI = 0). If the
polarity of the clock and/or the frame sync have been inverted, all the timing
remains valid by inverting the clock signal STCK/SRCK and/or the frame
sync STFS/SRFS shown in the tables and in the figures.
