SPI characteristics
Unless otherwise specified, the parameters given in Table 57 are derived from tests
performed under ambient temperature, fPCLKx frequency and VDD supply voltage conditions
summarized in Table 18: General operating conditions.
Refer to Section 6.3.14: I/O port characteristics for more details on the input/output alternate
function characteristics (NSS, SCK, MOSI, MISO for SPI and WS, CK).
