Serial Communications Interface (SCI) Module
11.10.3 SCI x Control Register 2 (SCIxC2)
This register can be read or written at any time.
TIE — Transmit Interrupt Enable (for TDRE)
TCIE — Transmission Complete Interrupt Enable (for TC)
RIE — Receiver Interrupt Enable (for RDRF)
ILIE — Idle Line Interrupt Enable (for IDLE)
TE — Transmitter Enable

TE must be 1 in order to use the SCI transmitter. Normally, when TE = 1, the SCI forces the TxD1 pin
to act as an output for the SCI system. If LOOPS = 1 and RSRC = 0, the TxD1 pin reverts to being a
port B general-purpose I/O pin even if TE = 1.
When the SCI is configured for single-wire operation (LOOPS = RSRC = 1), TXDIR controls the
direction of traffic on the single SCI communication line (TxD1 pin).
TE also can be used to queue an idle character by writing TE = 0 then TE = 1 while a transmission is
in progress. Refer to
When TE is written to 0, the transmitter keeps control of the port TxD1 pin until any data, queued idle,
or queued break character finishes transmitting before allowing the pin to revert to a general-purpose
I/O pin.
1 = Hardware interrupt requested when TDRE flag is 1.
0 = Hardware interrupts from TDRE disabled (use polling).
1 = Hardware interrupt requested when TC flag is 1.
0 = Hardware interrupts from TC disabled (use polling).
1 = Hardware interrupt requested when RDRF flag is 1.
0 = Hardware interrupts from RDRF disabled (use polling).
1 = Hardware interrupt requested when IDLE flag is 1.
0 = Hardware interrupts from IDLE disabled (use polling).
1 = Transmitter on.
0 = Transmitter off.
