(1)

fUCxCLK = 1/2tLO/HI with tLO/HI ≥ max(tVALID,MO(Master) + tSU,SI(eUSCI), tSU,MI(Master) + tVALID,SO(eUSCI)).

For the master's parameters tSU,MI(Master) and tVALID,MO(Master) refer to 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 14 and Figure 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 14

and Figure 15.
