LINSCI serial communication interface (LIN master only)

General description
The interface is externally connected to another device by three pins (see
block
Receive Data In (RDI) and Transmit Data Out (TDO):
●
●
●
Through these pins, serial data is transmitted and received as frames comprising:
●
●
●
●
This interface uses two types of baud rate generator:
●
●
SCLK: Transmitter Clock Output. This pin outputs the transmitter data clock for
synchronous transmission (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
peripherals that have shift registers (e.g. LCD drivers). The clock phase and polarity
are software programmable.
TDO: Transmit Data Output. When the transmitter is disabled, the output pin returns to
its I/O port configuration. When the transmitter is enabled and nothing is to be
transmitted, the TDO pin is at high level.
RDI: Receive Data Input is the serial data input. Oversampling techniques are used for
data recovery by discriminating between valid incoming data and noise.
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.
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.
