SPI characteristics
Unless otherwise specified, the parameters given in Table 36 are derived from tests per-
formed under the ambient temperature, fPCLKx frequency and VDD supply voltage condi-
tions summarized in Table 10.
Refer to subsubsec 5.3.12 for more details on the input/output alternate function charac-
teristics (NSS, SCK, MOSI, MISO).
