AC Waveforms
Two different timing diagrams are shown below. Waveform 1 shows the SCK signal
being low when CS makes a high-to-low transition, and Waveform 2 shows the SCK sig-
nal being high when CS makes a high-to-low transition. Both waveforms show valid
timing diagrams. The setup and hold times for the SI signal are referenced to the low-to-
high transition on the SCK signal.
Waveform 1 shows timing that is also compatible with SPI Mode 0, and Waveform 2
shows timing that is compatible with SPI Mode 3.
Waveform 1 – Inactive Clock Polarity Low and SPI Mode 0
Waveform 2 – Inactive Clock Polarity High and SPI Mode 3
