Bit 1 (UTBF): UART transfer buffer empty flag. Set to 1 when transfer buffer is empty.

Reset to 0 automatically when write into URTD register. UTBF bit will be cleared by

hardware when enabling transmission. And UTBF bit is read-only. Therefore, write URTD

Bit 0 (TXE): Enable transmission

0: Disable

1: Enable

Bit 7 (URTD8): UART transmit data bit 8. Write only.

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 happened, and clear to 0 by

software.

Bit 3 (OVERR): Over running error flag. Set to 1 when overrun error happened, and clear

to 0 by software.

Bit 2 (FMERR): Framing error flag. Set to 1 when framing error happen, and clear to 0 by

software.
