SPI interface characteristics
Unless otherwise specified, the parameters given in Table 103 for the SPI interface are
derived from tests performed under the ambient temperature, f
PCLKx
frequency and V
DD
supply voltage conditions summarized in Table 23: General operating conditions, with the
following configuration:
 Output speed
is set to OSPEEDRy[1:0] = 11
 Capacitive load C = 30 pF
 Measurement points are done at CMOS levels: 0.5V
DD
 I/O compensation cell enabled
 HSLV activated when VDD  2.7 V
Refer to Section 6.3.15: I/O port characteristics for more details on the input/output alternate
function characteristics (NSS,
SCK, MOSI, MISO for SPI).
