Figure 50. SPI timing diagram - master mode
1. Measurement points are done at CMOS levels: 0.3 VDD and 0.7 VDD.
SAI characteristics
Unless otherwise specified, the parameters given in Table 130 for SAI are derived from
tests performed under the ambient temperature, fPCLKx frequency and VDD supply voltage
conditions summarized inTable 27: General operating conditions, with the following configu-
ration:
•
Output speed is set to OSPEEDRy[1:0] = 10
•
Capacitive load C = 30 pF
•
Measurement points are done at CMOS levels: 0.5VDD
Refer to Section 5.3.15: I/O port characteristics for more details on the input/output alternate
function characteristics (CK,SD,FS).
