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
