These parameters are characterized but not tested in manufacturing.
Data in “Typical” column is at 3.3V, 25°C unless otherwise stated. Parameters are for design guidance only
and are not tested.
The minimum clock period for SCKx is 40 nsec. Therefore, the clock generated in Master mode must not
violate this specification.
Assumes 50 pF load on all SPIx pins.
