byte.

SAI characteristics

Unless otherwise specified, the parameters given in Table 207 for SAI are derived from tests

performed under the ambient temperature, fPCLKx frequency and VDD supply voltage

conditions summarized in Table 122: General operating conditions, with the following

configuration:

•

Output speed is set to OSPEEDRy[1:0] = 10

•

Capacitive load CL = 30 pF

•

IO Compensation cell activated.

•

Measurement points are done at CMOS levels: 0.5VDD

•

VOS level set to VOS1.

Refer to Section 7.3.15: I/O port characteristics for more details on the input/output

alternate function characteristics (SCK,SD,WS).
