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 clock generated in Master mode must not
violate this specification.
Assumes 50 pF load on all SPIx pins.
