Serial Communications Interface (SCI)
7.7.3 Serial Communications Control Register 2
Data Sheet
124
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
RWU — Receiver Wakeup Control Bit
SBK — Send Break
When TE goes from 0 to 1, one unit of idle character time (logic 1) is queued as
a preamble.
At least one character time of break is queued and sent each time SBK is written
to 1. As long as the SBK bit is set, break characters are queued and sent. More
than one break may be sent if the transmitter is idle at the time the SBK bit is
toggled on and off, as the baud rate clock edge could occur between writing
the 1 and writing the 0 to SBK.

Write:
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
