Writing a zero to this bit has no effect.
Writing a one to this bit will stop the generation of break signal characters, and then send ones for TTGR.TG duration, or at least
12 bit periods. No effect if no break is being transmitted.
Writing a zero to this bit has no effect.
Writing a one to this bit will start transmission of break characters when current characters present in THR and the transmit shift
register have been sent. No effect if a break signal is already being generated.
Writing a zero to this bit has no effect.
Writing a one to this bit will clear the following bits in CSR: PARE, FRAME, OVRE, LINBE, LINSFE, LINIPE, LINCE, LINSNRE,
and RXBRK.
Writing a zero to this bit has no effect.
Writing a one to this bit disables the transmitter.
Writing a zero to this bit has no effect.
Writing a one to this bit enables the transmitter if TXDIS is zero.
Writing a zero to this bit has no effect.
Writing a one to this bit disables the receiver.
Writing a zero to this bit has no effect.
Writing a one to this bit enables the receiver if RXDIS is zero.
Writing a zero to this bit has no effect.
Writing a one to this bit will reset the transmitter.
Writing a zero to this bit has no effect.
Writing a one to this bit will reset the receiver.
