See Figure 4, Figure 5, and Figure 6.
Guaranteed by design and characterization, not production tested.
In ISHA mode the maximum SCLK frequency is 20 MHz and the minimum pulse width is 20 ns.
These numbers are measured with the load circuit of Figure 3.
SYNC should be taken low while SCLK is low for read back.
