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 66.7 ns. Therefore, the clock generated in Master mode must not
violate this specification.
violate this specification.
4:
Assumes 50 pF load on all SPIx pins.
