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
wavforms 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
Waveform 2 – Inactive Clock Polarity High
