1: Writing a one to this bit will perform a software reset. This software reset has priority on any other bit in CR.
0: Writing a zero to this bit has no effect.
1: Writing a one to this bit will disable the transmission. If a character is currently being transmitted, the disable occurs at the end
of the current character transmission.
0: Writing a zero to this bit has no effect.
1: Writing a one to this bit will enable the transmission if the TXDIS bit is not written to one.
0: Writing a zero to this bit has no effect.
1: Writing a one to this bit will disable the reception. If a character is currently being received, the disable occurs at the end of
current character reception.
0: Writing a zero to this bit has no effect.
1: Writing a one to this bit will enables the reception if the RXDIS bit is not written to one.
0: Writing a zero to this bit has no effect.
