10.8 LINSCI SERIAL COMMUNICATION INTERFACE (LIN Master Only)
10.8.1 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.

10.8.3 General Description
The interface is externally connected to another
device by three pins (see
Any SCI bidirectional communication requires a
minimum of two pins: Receive Data In (RDI) and
Transmit Data Out (TDO):
– SCLK: Transmitter clock output. This pin outputs
– TDO: Transmit Data Output. When the transmit-
– RDI: Receive Data Input is the serial data input.
Through these pins, serial data is transmitted and
received as frames comprising:
– An Idle Line prior to transmission or reception
– A start bit
– A data word (8 or 9 bits) least significant bit first
– A Stop bit indicating that the frame is complete.
This interface uses two types of baud rate generator:
– A conventional type for commonly-used baud
– An extended type with a prescaler offering a very
the transmitter data clock for synchronous trans-
mission (no clock pulses on start bit and stop bit,
and a software option to send a clock pulse on
the last data bit). This can be used to control pe-
ripherals that have shift registers (e.g. LCD driv-
ers). The clock phase and polarity are software
programmable.
ter is disabled, the output pin returns to its I/O
port configuration. When the transmitter is ena-
bled and nothing is to be transmitted, the TDO
pin is at high level.
Oversampling techniques are used for data re-
covery by discriminating between valid incoming
data and noise.
