10.5 LINSCI SERIAL COMMUNICATION INTERFACE (LIN MASTER/SLAVE)
10.5.1 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 of-
fers 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.
