SPI interface characteristics

Unless otherwise specified, the parameters given in Table 50 are preliminary values derived

from tests performed under the ambient temperature, fPCLKx frequency and VDD supply

voltage conditions summarized in Table 9.

Refer to Section 5.3.13: I/O current injection characteristics for more details on the

input/output alternate function characteristics (NSS, SCK, MOSI, MISO).

1. Preliminary values.

2. Min time is for the minimum time to drive the output and the max time is for the maximum time to validate

the data.

3. Min time is for the minimum time to invalidate the output and the max time is for the maximum time to put

the data in Hi-Z
