Note 1:
These parameters are characterized, but are not tested in manufacturing.
2:
Data in “Typical” column is at 3.3V, +25°C unless otherwise stated.
3:
The minimum clock period for SCK2 is 91 ns. Therefore, the SCK2 clock generated by the master must
not violate this specification.
not violate this specification.
