Bit 7 = TIE Transmitter interrupt enable
This bit is set and cleared by software.
0: Interrupt is inhibited
1: In 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
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
Bit 3 = TE Transmitter enable
This bit enables the transmitter. It is set and
cleared by software.
0: Transmitter is disabled
1: Transmitter is enabled
Notes:
– During transmission, a “0” pulse on the TE bit
– When TE is set there is a 1 bit-time delay before
Bit 2 = RE Receiver enable
This bit enables the receiver. It is set and cleared
by software.
0: Receiver is disabled in the SCISR register

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
Note: If the SBK bit is set to “1” and then to “0”, the
transmitter will send a BREAK word at the end of
the current word.
DATA REGISTER (SCIDR)
Read/Write
Reset Value: Undefined
Contains the Received or Transmitted data char-
acter, depending on whether it is read from or writ-
ten to.
The Data register performs a double function (read
and write) since it is composed of two registers,
one for transmission (TDR) and one for reception
(RDR).
The TDR register provides the parallel interface
between the internal bus and the output shift reg-
ister (see
The RDR register provides the parallel interface
between the input shift register and the internal
bus (see

bit) the SCI must first receive a data byte, other-

up by Idle line detection.

ified by software while the RDRF bit is set.
