Waveforms 1 and 2 are compatible with SPI Mode 0 and SPI Mode 3, respectively.
Waveform 3 and waveform 4 illustrate general timing diagram for RapidS serial interface. These are similar to
waveform 1 and waveform 2, except that output SO is not restricted to become valid during the t
timing waveforms are valid over the full frequency range (maximum frequency = 66MHz) of the RapidS serial case.
