(1) The DCO wake-up time must be considered in LPM3 and LPM4 for baud rates above 1 MHz.
(2) 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.
