U = Unaffected by reset
If M is set, R8 stores the ninth bit of the receive data character.
If M is set, T8 stores the ninth bit of the transmit data character.
When TE goes from zero to one, one unit of idle character time (logic one) is queued as a preamble.
0 = 1 start bit, 8 data bits, 1 stop bit
1 = 1 start bit, 9 data bits, 1 stop bit
0 = Wake up by IDLE line recognition
1 = Wake up by address mark
0 = TDRE interrupts disabled
1 = SCI interrupt requested when the TDRE flag is set
0 = TC interrupts disabled
1 = SCI interrupt requested when the TC flag is set
0 = RDRF and OR interrupts disabled
1 = SCI interrupt requested when the RDRF flag or the OR flag is set
0 = IDLE interrupts disabled
1 = SCI interrupt requested when IDLE status flag is set
0 = Transmitter disabled
1 = Transmitter enabled
0 = Receiver disabled
1 = Receiver enabled
