AC Waveforms
Six different timing waveforms are shown on
low transition, and waveform 2 shows the SCK signal being high when CS makes a high-to-low transition. In both cases, output
SO becomes valid while the SCK signal is still low (SCK low time is specified as t
RapidS serial interface, but for frequencies up to 66MHz. 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
over the full frequency range (maximum frequency = 66MHz) of the RapidS serial case.
