(1) f_UCxCLK = 1/2 t_LO/HI with t_LO/HI ≥ max(t_{VALID,MO(Master)} + t_SU,SI(eUSCI), t_{SU,MI(Master)} + t_{VALID,SO(eUSCI)})
For the master parameters t_{SU,MI(Master)} and t_{VALID,MO(Master)}, see the SPI parameters of the attached master.

(2) Specifies the time to drive the next valid data to the SOMI output after the output changing UCLK clock edge. See the timing diagrams in Figure 8-14 and Figure 8-15.

(3) Specifies how long data on the SOMI output is valid after the output changing UCLK clock edge. See the timing diagrams in Figure 8-14 and Figure 8-15.
