The SCCR2 register provides the control bits that enable or disable individual SCI functions.
TIE — Transmit interrupt enable
1 (set) – SCI interrupt requested when TDRE status flag is set.
0 (clear) – TDRE interrupts disabled.
TCIE — Transmit complete interrupt enable
5
1 (set) – SCI interrupt requested when TC status flag is set.
0 (clear) – TC interrupts disabled.
RIE — Receiver interrupt enable
1 (set) – SCI interrupt requested when RDRF flag or the OR status flag is set.
0 (clear) – RDRF and OR interrupts disabled.
ILIE — Idle line interrupt enable
1 (set) – SCI interrupt requested when IDLE status flag is set.
0 (clear) – IDLE interrupts disabled.
TE — Transmitter enable
1 (set) – Transmitter enabled.
0 (clear) – Transmitter disabled.
RE — Receiver enable
1 (set) – Receiver enabled.
0 (clear) – Receiver disabled.
RWU — Receiver wake-up control
1 (set) – Wake-up enabled and receiver interrupts inhibited.
0 (clear) – Normal SCI receiver.
SBK — Send break
1 (set) – Break codes generated as long as SBK is set.
0 (clear) – Break generator off.
