SPI serial peripheral interface
Unless otherwise specified, the parameters given in Table 54 are derived from tests
performed under ambient temperature, fMASTER frequency and VDD supply voltage
conditions. tMASTER = 1/fMASTER.
Refer to I/O port characteristics for more details on the input/output alternate function
characteristics (NSS, SCK, MOSI, MISO).

1.
fMAX is fMASTER/2.
2.
The pad has to be configured accordingly (fast mode).
3.
Values based on design simulation and/or characterization results, and not tested in production.
4.
Min time is for the minimum time to drive the output and the max time is for the maximum time to validate the data.
5.
Min time is for the minimum time to invalidate the output and the max time is for the maximum time to put the data in Hi-Z.
