Always reads 0
Always read 0
0 = SCI transmitter configured for 8-bit data characters.
1 = If M bit is set, R8 stores the ninth data bit in the transmit data
0 = Start bit, 8 data bits, 1 stop bit
1 = Start bit, 9 data bits, 1 stop bit
0 = Wakeup by IDLE line recognition
1 = Wakeup by address mark (most significant data bit set)
0 = TDRE interrupts disabled
1 = SCI interrupt requested when TDRE status flag is set
0 = TC interrupts disabled
1 = SCI interrupt requested when TC status flag is set
0 = RDRF and OR interrupts disabled
1 = SCI interrupt requested when RDRF flag or the OR status 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
0 = Normal SCI receiver
1 = Wakeup enabled and receiver interrupts inhibited
0 = Break generator off
1 = Break codes generated as long as SBK = 1
