Bit 7 (URRD8): Receiving Data Bit 8  
Bit 6 (EVEN): Select Parity Check  
0 : Odd parity  
1 : Even parity  
Bit 5 (PRE):  
Enable Parity Addition  
0 : Disable  
1 : Enable  
Bit 4 (PRERR): Parity Error Flag  
Set to 1 when parity error occurs and cleared to 0 by software.  
Bit 3 (OVERR): Over Running Error Flag  
Set to 1 when overrun error occurs and cleared to 0 by software.  
Bit 2 (FMERR): Framing Error Flag  
Set to 1 when framing error occurs and cleared to 0 by software.  
Bit 1 (URBF): UART Read Buffer Full Flag  
Set to 1 when one character is received. Reset to 0 automatically  
when read from URS register. URBF will be cleared by hardware  
when enabling receiving. And URBF bit is read-only. Therefore,  
reading the URS register is necessary to avoid overrun error.  
Bit 0 (RXE):  
Enable Receiving  
0 : Disable  
1 : Enable
