0 = No effect.

1 = The receiver is enabled if RXDIS is 0.

0 = No effect.

1 = The receiver is disabled. If a character is being processed and RSTRX is not set, the character is completed before the 
receiver is stopped.

0 = No effect.

1 = The transmitter is enabled if TXDIS is 0. 

0 = No effect. 

1 = The transmitter is disabled. If a character is being processed and a character has been written in the UART_THR and RSTTX 
is not set, both characters are completed before the transmitter is stopped.
