SPI serial peripheral interface

Unless otherwise specified, the parameters given in Table 52 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).
