1. Guaranteed by characterization results.
2. Maximum 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 %.
3. SPI mapped on Port G.
