10.3.9
SPI serial peripheral interface
Unless otherwise specified, the parameters given in Table 40 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).
