Note 1: These parameters are characterized, but not tested in manufacturing.
2: Data in “Typical” column is at 3.3V, 25°C unless otherwise stated. Parameters are for design guidance only
and are not tested.
3: The minimum clock period for SCKx is 40 nsec. Therefore, the clock generated in Master mode must not
violate this specification.
4: Assumes 50 pF load on all SPIx pins.
