Bit 7 = TIE Transmitter interrupt enable.
This bit is set and cleared by software.
0: Interrupt is inhibited
1: An SCI interrupt is generated whenever
Bit 6 = TCIE Transmission complete interrupt ena-
ble
This bit is set and cleared by software.
0: Interrupt is inhibited
1: An SCI interrupt is generated whenever TC=1 in
Bit 5 = RIE Receiver interrupt enable.
This bit is set and cleared by software.
0: Interrupt is inhibited
1: An SCI interrupt is generated whenever OR=1
Bit 4 = ILIE Idle line interrupt enable.
This bit is set and cleared by software.
0: Interrupt is inhibited
1: An SCI interrupt is generated whenever IDLE=1
Bit 3 = TE Transmitter enable.
This bit enables the transmitter. It is set and
cleared by software.
0: Transmitter is disabled, the TDO pin is in high
1: Transmitter is enabled
Note: during transmission, a “0” pulse on the TE
bit (“0” followed by “1”) sends a preamble after the
current word.
Bit 2 = RE Receiver enable.
This bit enables the receiver. It is set and cleared
by software.
0: Receiver is disabled, it resets the RDRF, IDLE,
1: Receiver is enabled and begins searching for a

Bit 1 = RWU Receiver wake-up.
This bit determines if the SCI is in mute mode or
not. It is set and cleared by software and can be
cleared by hardware when a wake-up sequence is
recognized.
0: Receiver in active mode
1: Receiver in mute mode
Bit 0 = SBK Send break.
This bit set is used to send break characters. It is
set and cleared by software.
0: No break character is transmitted
1: Break characters are transmitted

Bit 7 = Reserved
Bit 6 = LINE LIN mode Enable.
This bit is set and cleared by software.
0: LIN master mode disabled
1: LIN master mode enabled
LIN master mode enables the capability to send
LIN Synch Breaks (13 low bits) using the SBK bit
in the SCICR2 register. In transmission, the LIN
