Notes:
16.
This parameter is guaranteed by design, but not production tested.
17.
Rise and Fall time of incoming DI, CS, and SCLK signals suggested for design consideration to prevent the occurrence of double pulsing.
18.
Time required for output status data to be available for use at DO pin.
19.
Time required for output status data to be terminated at DO pin
20.
Time required to obtain valid data out from DO following the rise of SCLK.
