(1) f_UCxCLK = 1/2t_LO/HI with t_LO/HI ≥ max(t_{VALID,MO(Master)} + t_SU,SI(USCI), t_{SU,MI(Master)} + t_{VALID,SO(USCI)}).
For the master's parameters t_{SU,MI(Master)} and t_{VALID,MO(Master)}, see the SPI parameters of the attached slave.
(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 11 and Figure 12.
(3) Specifies how long data on the SOMI output is valid after the output changing UCLK clock edge. See the timing diagrams in Figure 11
and Figure 12.
