SPI/I2S characteristics
Unless otherwise specified, the parameters given in Table 59 for SPI or in Table 60 for I2S
are derived from tests performed under ambient temperature, fPCLKx frequency and VDD
supply voltage conditions summarized in Table 15: General operating conditions.
Refer to Section 6.3.13: I/O port characteristics for more details on the input/output alternate
function characteristics (NSS, SCK, MOSI, MISO for SPI and WS, CK, SD for I2S).
