<description>Received Noise interrupt flag. Three samples of received data are taken in order to determine the value of each received data bit, except in synchronous mode. This acts as a noise filter if one sample disagrees. This flag is set when a received data bit contains one disagreeing sample. This could indicate line noise, a baud rate or character format mismatch, or loss of synchronization during data reception.</description>
