Communication interfaces
Serial peripheral interface (SPI)
Unless otherwise specified, the parameters given in Table 31 are derived from tests
performed under ambient temperature, fMASTER frequency and VDD supply voltage
conditions summarized in Section 9.3.1. Refer to I/O port characteristics for more details on
the input/output alternate function characteristics (NSS, SCK, MOSI, MISO).

1.
Parameters are given by selecting 10 MHz I/O output frequency.
2.
Values based on design simulation and/or characterization results, and not tested in production.
3.
Min time is for the minimum time to drive the output and the max time is for the maximum time to validate the data.
4.
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.
