AC Waveforms
Four different timing waveforms are shown in
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
and 2 are compatible with SPI Mode 0 and SPI Mode 3, respectively.
Waveform 3 and 4 illustrate general timing diagram for RapidS serial interface. These are similar to Waveform 1 and 2,
except that output SO is not restricted to become valid during the t
full frequency range (maximum frequency = 85MHz) of the RapidS serial case.
