Longer SCLK cycle time is required for correct operation of readback mode; consult timing diagrams and timing specifications.
Guaranteed by design and characterization, not production tested.
All input signals are specified with t
See Figure 4 and Figure 5.
This is measured with the load circuit shown in Figure 2.
