SPI characteristics
Unless otherwise specified, the parameters given in the following table are derived from
tests performed under ambient temperature, f
conditions summarized in
Refer to
input/output alternate function characteristics (NSS, SCK, MOSI, MISO).
Table 49.
1. The characteristics above are given for voltage range 1.
2. Based on characterization, not tested in production.
3. The maximum SPI clock frequency in slave transmitter mode is given for an SPI slave input clock duty
4. Min time is for the minimum time to drive the output and max time is for the maximum time to validate the
