Although this noise does not affect proper synchronization with the start
bit time, it does set the noise flag.

that resets the RT clock. The sample after the reset is low but is not
preceded by three high samples that would qualify as a falling edge.
Depending on the timing of the start bit search and on the data, the frame
may be missed entirely or it may set the framing error flag.
