2.11.3 Frame Error on a Previous Message May Cause False Start Bit Detection
A false start bit detection will trigger if receiving a frame with RXDATAH.FERR set and reading the RXDATAL before the RxD line goes high.
Work Around
Wait for the RXD pin to go high before reading RXDATA by, for instance, polling the bit in PORTn.IN where the RXD pin is located.
