SCI serial communication interface
Introduction
The serial communications interface (SCI) offers a flexible means of full-duplex data
exchange with external equipment requiring an industry standard NRZ asynchronous serial
data format. The SCI offers a very wide range of baud rates using two baud rate generator
systems.

General description
The interface is externally connected to another device by three pins (see
SCI bidirectional communication requires a minimum of two pins: Receive Data In (RDI) and
Transmit Data Out (TDO):
●
Full-duplex, asynchronous communications
NRZ standard format (Mark/Space)
Dual baud rate generator systems
Independently programmable transmit and receive baud rates up to 500K baud
Programmable data word length (8 or 9 bits)
Receive buffer full, Transmit buffer empty and End of Transmission flags
2 receiver wake-up modes:
–
–
Muting function for multiprocessor configurations
Separate enable bits for Transmitter and Receiver
4 error detection flags:
–
–
–
–
5 interrupt sources with flags:
–
–
–
–
–
Parity control:
–
–
Reduced power consumption mode
SCLK: Transmitter clock output. This pin outputs the transmitter data clock for
synchronous transmission (no clock pulses on start bit and stop bit, and a software
option to send a clock pulse on the last data bit). This can be used to control
Address bit (MSB)
Idle line
Overrun error
Noise error
Frame error
Parity error
Transmit data register empty
Transmission complete
Receive data register full
Idle line received
Overrun error detected
Transmits parity bit
Checks parity of received data byte
