Sample tested during initial release and after any redesign or process change
that may affect this parameter. All input signals are specified with tr = tf = 5 ns
(10% to 90%) and timed from a voltage level of 1.6 V.

See timing diagrams below and Serial Interface section of this data sheet.
Minimum time between read command and data read for all registers except
wavmode register, which is t 9 = 500 ns min.
Measured with the load circuit in Figure 1 and defined as the time required for
the output to cross 0.8 V or 2.4 V.
Derived from the measured time taken by the data outputs to change 0.5 V
