1. Guaranteed by characterization results.
2. Maximum frequency in Slave transmitter mode is determined by the sum of t
v(SO)
and t
su(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 t
su(MI)
= 0 while Duty(SCK) = 50%
