(1) Pulses on the UART receive input (UCxRX) shorter than the UART receive deglitch time are suppressed. To ensure that pulses are
correctly recognized, their duration should exceed the maximum specification of the deglitch time.

(1) f_UCxCLK = 1/2t_LO/HI with t_LO/HI ≥ max(t_{VALID,MO(USCI)} + t_SU,SI(Slave), t_SU,MI(USCI) + t_{VALID,SO(Slave)}).
For the slave's parameters t_SU,SI(Slave) and t_{VALID,SO(Slave)} see 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. See the timing diagrams
in Figure 15 and Figure 16.
(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. See the timing diagrams in
Figure 15 and Figure 16.
