These parameters are characterized but not tested in manufacturing.
Data in “Typ” column is at 5V, 25°C unless otherwise stated. Parameters are for design guidance only and
are not tested.
The minimum clock period for SCK is 100 ns. Therefore, the clock generated in master mode must not
violate this specification.
Assumes 50 pF load on all SPI pins.
