Electrical characteristics

SPI/I2S characteristics

Unless otherwise specified, the parameters given in Table 63 for SPI or in Table 64 for I2S

are derived from tests performed under ambient temperature, fPCLKx frequency and VDD

supply voltage conditions summarized in Table 24.

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, SD for I2S).
