t
Six different timing waveforms are shown on
low when CS makes a high-to-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 66 MHz. 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
imum frequency = 66 MHz) of the RapidS serial case.
