Guaranteed by design and characterization; not production tested.
All input signals are specified with t
See Figure 5 and Figure 6.
Writes to more than one X1 register engages the calibration engine for longer times, shown by the BUSY low time, t
should either be timed or should wait until BUSY returns high (see Figure 56). This is required to ensure that data is not lost or overwritten.

SDO output slows with lower DVCC supply and may require use of a slower SCLK.
