Serial communications interface (SCI)
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 two pins (see
●
●
– 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
– Parity error
– Transmits parity bit
– Checks parity of received data byte
Full duplex, asynchronous communications
NRZ standard format (Mark/Space)
Independently programmable transmit and receive baud rates up to 250K baud.
Programmable data word length (8 or 9 bits)
Receive buffer full, Transmit buffer empty and End of Transmission flags
Two receiver Wakeup modes:
Muting function for multiprocessor configurations
Separate enable bits for Transmitter and Receiver
Four error detection flags:
Six interrupt sources with flags:
Parity control:
Reduced power consumption mode
TDO: Transmit Data output. When the transmitter and the receiver are disabled, the
output pin returns to its I/O port configuration. When the transmitter and/or the receiver
are enabled and nothing is to be transmitted, the TDO pin is at high level.
RDI: Receive Data input is the serial data input. Oversampling techniques are used for
data recovery by discriminating between valid incoming data and noise.
