SPI characteristics
Unless otherwise specified, the parameters given in Table 78 are under the ambient
temperature, fPCLKx frequency and supply voltage conditions summarized in Table 26, with
the following configuration:
•
Output speed is set to OSPEEDRy[1:0] = 10
•
Capacitive load CL = 30 pF
•
Measurement points are done at 0.5 x VDD
•
I/O compensation cell activated
Refer to Section 5.3.16 for more details on the I/O input/output characteristics (NSS, SCK,
MOSI, MISO for SPI).
