(1)
fUCxCLK = 1/2tLO/HI with tLO/HI ≥ max(tVALID,MO(USCI) + tSU,SI(Slave), tSU,MI(USCI) + tVALID,SO(Slave)).
For the slave's parameters tSU,SI(Slave) and tVALID,SO(Slave) refer to the SPI parameters of the attached slave.
(2)
Specifies the time to drive the next valid data to the SIMO 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 SIMO output is valid after the output changing UCLK clock edge. Negative values indicate that the data
on the SIMO output can become invalid before the output changing clock edge observed on UCLK. Refer to the timing diagrams in
Figure 11. SPI Master Mode, CKPH = 0
