1. Evaluated by characterization, not tested in production.

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 %.
