SPI interface characteristics
Unless otherwise specified, the parameters given in Table 64 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 set to OSPEEDRy[1:0] = 10
capacitive load C = 30 pF
measurement points at CMOS levels: 0.5 VDD
Refer to Section 5.3.20 for more details on the input/output alternate function characteristics
(NSS, SCK, MOSI, MISO for SPI).
2. Spikes with widths below tAF(min) are filtered.
3. Spikes with widths above tAF(max) are not filtered
