LINSCI serial communication interface (LIN master

only)

16.1

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.

●

●

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

●

Transmitter clock output

●

Parity control:

–

Transmits parity bit

–

Checks parity of received data byte
