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 signal 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
