PAREN=dis, PARMD=1, STOP=1, SIZE=5, PAREO=Even
Control Register.
| RXTHD | Receive Threshhold. |
| PAREN | Enable/disable Parity bit (9th character). 0 (dis): No Parity 1 (en): Parity enabled as 9th bit |
| PAREO | When PARITY_EN=1, selects odd or even parity. 0 (Even): Even parity selected. 1 (ODD): Odd parity selected. |
| PARMD | Selects parity based on 1s or 0s count (when PARITY_EN=1). 0 (1): Parity calculation is based on number of 1s in frame. 1 (0): Parity calculation is based on number of 0s in frame. |
| TXFLUSH | Flushes the TX FIFO buffer. |
| RXFLUSH | Flushes the RX FIFO buffer. |
| SIZE | Selects UART character size. 0 (5): 5 bits. 1 (6): 6 bits. 2 (7): 7 bits. 3 (8): 8 bits. |
| STOP | Selects the number of stop bits that will be generated. 0 (1): 1 stop bit. 1 (1_5): 1.5 stop bits. |
