Serial Communications Interface (SCI)
7.8.3 Serial Communications Control Register 2
Technical Data
154
Address:
The SCCR2 register provides the control bits that enable or disable
individual SCI functions.
TIE — Transmit Interrupt Enable Bit
TCIE — Transmit Complete Interrupt Enable Bit
RIE — Receiver Interrupt Enable Bit
ILIE — Idle-Line Interrupt Enable Bit
TE — Transmitter Enable Bit
RE — Receiver Enable Bit

Reset:
Read:
Write:
When TE goes from 0 to 1, one unit of idle character time (logic 1) is
queued as a preamble.
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
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
