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.
Main features
● 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
– Address bit (MSB)
– Idle line
● Muting function for multiprocessor configurations
● Separate enable bits for Transmitter and Receiver
● 4 error detection flags
– Overrun error
– Noise error
– Frame error
– Parity error
● 5 interrupt sources with flags
– Transmit data register empty
– Transmission complete
– Receive data register full
– Idle line received
– Overrun error detected
