Note 1: Data in “Typ” column is at 3.3V, 25°C unless otherwise stated. Parameters are for design guidance only and
are not tested.
2: The minimum clock period for SCKx is 100 ns. Therefore, the clock generated in Master mode must not
violate this specification.
3: Assumes 50 pF load on all SPIx pins.
