SPI interface characteristics

Unless otherwise specified, the parameters given in Table 98 for the SPI interface are

derived from tests performed under the ambient temperature, fpclkx frequency and VDD

supply voltage conditions summarized in Table 13: 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: 0.5×VDD

•

I/O compensation cell enabled

•

HSLV activated when VDD ≤ 2.7 V

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).
