The SCCR2 register provides the control bits that enable or disable
individual SCI functions.
TIE — Transmit interrupt enable
1 = SCI interrupt requested when TDRE status flag is set.
0 = TDRE interrupts disabled.
TCIE — Transmit complete interrupt enable
1 = SCI interrupt requested when TC status flag is set.
0 = TC interrupts disabled.
RIE — Receiver interrupt enable
1 = SCI interrupt requested when RDRF flag or the OR status flag
is set.
0 = RDRF and OR interrupts disabled.
ILIE — Idle line interrupt enable
1 = SCI interrupt requested when IDLE status flag is set.
0 = IDLE interrupts disabled.
TE — Transmitter enable
1 = Transmitter enabled.
0 = Transmitter disabled.
RE — Receiver enable
1 = Receiver enabled.
0 = Receiver disabled.
RWU — Receiver wakeup control
1 = Wakeup enabled and receiver interrupts inhibited.
0 = Normal SCI receiver.
SBK — Send break
1 = Break codes generated as long as SBK is set.
