LINSCI serial communication interface (LIN master/slave)

15 LINSCI serial communication interface (LIN
master/slave)
15.1

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.
The LIN-dedicated features support the LIN (Local Interconnect Network) protocol for both
master and slave nodes.
This chapter is divided into SCI Mode and LIN mode sections. For information on general
SCI communications, refer to the SCI mode section. For LIN applications, refer to both the
SCI mode and LIN mode sections.
