Notes
24.
RST
low duration measured with outputs enabled and going to OFF or disabled condition.
25.
Maximum setup time required for the 33984 is the minimum guaranteed time needed from the microcontroller.
26.
Rise and Fall time of incoming SI, CS, and SCLK signals suggested for design consideration to prevent the occurrence of double pulsing.
27.
Time required for output status data to be available for use at SO. 1.0 k
on pullup on CS.
28.
Time required for output status data to be terminated at SO. 1.0 k
on pullup on CS.
29.
Time required to obtain valid data out from SO following the rise of SCLK.
