LINSCI SERIAL COMMUNICATION INTERFACE (Cont’d)

9.5.4 General Description

The interface is externally connected to another

device by two pins:

– TDO: Transmit Data Output. When the transmit-

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.

– A conventional type for commonly-used baud

rates.

– An extended type with a prescaler offering a very

wide range of baud rates even with non-standard

oscillator frequencies.

– A LIN baud rate generator with automatic resyn-

chronization.

– RDI: Receive Data Input is the serial data input.

Oversampling techniques are used for data re-

covery by discriminating between valid incoming

data and noise.

Through these pins, serial data is transmitted and

received as characters 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 character is com-

plete.

This interface uses three types of baud rate gener-

ator:

104/294
