These parameters are characterized but not tested in manufacturing.

Data in “Typ” column is at 3.3V, 25°C unless otherwise stated.

The minimum clock period for SCKx is 100 ns. Therefore, the clock generated in Master mode must not

violate this specification.

Assumes 50 pF load on all SPIx pins.
