These parameters are characterized, but are not tested in manufacturing.
Data in “Typ” column is at 3.3V, 25°C unless otherwise stated.
The minimum clock period for SCKx is 66.7 ns. Therefore, the SCK clock generated by the Master must
not violate this specificiation.
Assumes 50 pF load on all SPIx pins.
