1. Guaranteed by characterization results.
2. The 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 1.08V. SPI is tested in this voltage.
