SPI interface characteristics
Unless otherwise specified, the parameters given in Table 62 for the SPI interface are
derived from tests performed under the ambient temperature, fPCLKx frequency and VDD
supply voltage conditions summarized in Table 17, with the following configuration:
•
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 6.3.17: I/O port characteristics for more details on the input/output alternate
function characteristics (NSS, SCK, MOSI, MISO for SPI).
