1. Guaranteed by characterization results.

2. The maximum SPI clock frequency in slave transmitter mode is determined by the sum of tv(SO) and tsu(MI) which has to fit

into SCK low or high phase preceding the SCK sampling edge. This value can be achieved when the SPI communicates

with a master having tsu(MI) = 0 while Duty(SCK) = 50%.
