(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 width 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 parameters t_SU,SI(Slave) and t_{VALID,SO(Slave)}, see the SPI parameters of the attached slave.
