6.7.3 SCI Control Register 2
The SCI control register 2 (SCCR2) provides the control bits that enable or disable
individual SCI functions.
TIE — Transmit Interrupt Enable Bit
1 = TDRE interrupts disabled
1 = SCI interrupt requested when TDRE status flag is set
TCIE — Transmit Complete Interrupt Enable Bit
0 = TC interrupts disabled
1 = SCI interrupt requested when TC status flag is set
RIE — Receiver Interrupt Enable Bit
0 = RDRF and OR interrupts disabled
1 = SCI interrupt requested when RDRF flag or the OR status flag is set
ILIE — Idle Line Interrupt Enable Bit
1 = IDLE interrupts disabled
1 = SCI interrupt requested when IDLE status flag is set
TE — Transmitter Enable Bit
When TE goes from 0 to 1, one unit of idle character time (logic 1) is queued as
a preamble.
0 = Transmitter disabled
1 = Transmitter enabled
RE — Receiver Enable Bit
0 = Receiver disabled
1 = Receiver enabled
RWU — Receiver Wakeup Control Bit
0 = Normal SCI receiver
1 = Wakeup enabled and receiver interrupts inhibited
SBK — Send Break Bit
At least one character time of break is queued and sent each time SBK is written
to 1. 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.
0 = Break generator off
1 = Break codes generated as long as SBK = 1
