RIE — Receiver Interrupt Enable
ILIE — Idle Line Interrupt Enable
TE — Transmitter Enable
RE — Receiver Enable
RWU — Receiver Wake-Up Control
SBK — Send Break
As long as SBK remains set the transmitter will send zeros. When
SBK is changed to zero, the current frame of all zeros is finished
before the TxD line goes to the idle state. If SBK is toggled on and off,
the transmitter will send only 10 (or 11) zeros and then revert to mark
idle or sending data.
0 = RDRF and OR interrupts disabled, RAF interrupt in WAIT mode
1 = SCI interrupt will be requested whenever the RDRF or OR
0 = IDLE interrupts disabled
1 = SCI interrupt will be requested whenever the IDLE status flag
0 = Transmitter disabled
1 = SCI transmit logic is enabled and the TXD pin (Port S bit 1/bit
0 = Receiver disabled
1 = Enables the SCI receive circuitry.
0 = Normal SCI Receiver
1 = Enables the wake-up function and inhibits further receiver
0 = Break generator off
1 = Generate a break code (at least 10 or 11 contiguous zeros).

automatically clearing this bit.
