fUCxCLK = 1/2×tLO/HI with tLO/HI ≥ max(tVALID,MO(Master) + tSU,SI(USCI), tSU,MI(Master) + tVALID,SO(USCI)).
For the master's parameters tSU,MI(Master) and tVALID,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. Refer to 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. Refer to the timing diagrams in
Figure 13. SPI Slave Mode, CKPH = 0
