Note 1: These parameters are characterized, but are not tested in manufacturing.
2: Data in “Typ” column is at 3.3V, 25°C unless otherwise stated.
3: The minimum clock period for SCKx is 91 ns. Therefore, the SCK clock generated by the Master must not
violate this specificiation.
4: Assumes 50 pF load on all SPIx pins.
