and a non-inverted frame sync (TFSI=0 in SCR2 and RFSI=0 in SCSR). If the polarity of the clock and/or the frame sync have
been inverted, all the timings remain valid by inverting the clock signal STCK/SRCK and/or the frame sync STFS/SRFS in the
tables and in the figures.
All the timings for the SSI are given for a non-inverted serial clock polarity (TSCKP=0 in SCR2 and RSCKP=0 in SCSR)
