Figure 35. SPI – transfer timing diagram

The SPI can be driven by a microcontroller with its SPI peripheral running in the following mode:

CPOL = 0 and CPHA = 0.

For this mode input data is sampled by the low to high transition of the clock CLK, and output data is changed

from the high to low transition of CLK.
