RST Low duration measured with outputs enabled and going to OFF or disabled condition.
Rise and Fall time of incoming SI, CS, and SCLK signals suggested for design consideration to prevent the occurrence of double pulsing.
Time required for output status data to be available for use at the SO pin.
Time required for output status data to be terminated at the SO pin.
Time required to obtain valid data out from SO following the rise of SCLK. See (Note 4).
