0 No framing error detected
1 Byte received with incorrect stop bit level
Note that TCON.URX1IF and U1CSR.RX_BYTE bit will be asserted when the
first stop bit is checked OK, meaning that if two stop bits are sent and the
second stop bit is not OK, this bit is asserted 1 bit duration later than the 2 other
above mentioned bits.
