1. Master mode is internally generated clocks and frame syncs
2. Max clock frequency is IP_clk/4 = 60MHz / 4 = 15MHz for an 120MHz part.
3. All the timings for the ESSI are given for a non-inverted serial clock polarity (TSCKP=0 in SCR2 and RSCKP=0 in SCSR)
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 SCK/SC0 and/or the frame sync SC2/SC1 in
the tables and in the figures.
4. 50 percent duty cycle
5. bl = bit length; wl = word length
