Guaranteed by characterization results. 2. Excepting SPI1 with SCK IO=PA5. In this configuration, the maximum achievable frequency is 40 MHz. 3. Maximum frequency of the slave transmitter is determined by sum of Tv(SO) and Tsu(MI) intervals which has to fit into SCK level phase preceding the SCK sampling edge.This value can be achieved when it communicates with a Master having Tsu(MI)=0 while signal Duty(SCK)=50%.
