11.5 LINSCI SERIAL COMMUNICATION INTERFACE (LIN MASTER/SLAVE)
11.5.1 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.
11.5.2 SCI Features
Full duplex, asynchronous communications
NRZ standard format (Mark/Space)
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
Overrun, Noise and Frame error detection
6 interrupt sources
– Transmit data register empty
– Transmission complete
– Receive data register full
– Idle line received
– Overrun error
– Parity interrupt
Parity control:
– Transmits parity bit
– Checks parity of received data byte
Reduced power consumption mode
11.5.3 LIN Features
– LIN Master
– 13-bit LIN Synch Break generation
– LIN Slave
– Automatic Header Handling
– Automatic baud rate resynchronization based
on recognition and measurement of the LIN
Synch Field (for LIN slave nodes)
– Automatic baud rate adjustment (at CPU fre-
quency precision)
– 11-bit LIN Synch Break detection capability
– LIN Parity check on the LIN Identifier Field
(only in reception)
– LIN Error management
– LIN Header Timeout
– Hot plugging support
