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 GPIOG port which is supplied by VDDIO2 specified down to 1.08 V. SPI is tested in this voltage.
