The LIN Mode provides Master node and Slave node connectivity on a LIN bus.
The LIN (Local Interconnect Network) is a serial communication protocol which efficiently sup-
ports the control of mechatronic nodes in distributed automotive applications.
The main properties of the LIN bus are:
LIN provides cost efficient bus communication where the bandwidth and versatility of CAN are
not required.
The LIN Mode enables processing LIN frames with a minimum of action from the
microprocessor.
The USART can act either as a LIN Master node or as a LIN Slave node.
The node configuration is chosen by setting the MODE field in the Mode Register (MR):
In order to avoid unpredicted behavior, any change of the LIN node configuration must be fol-
lowed by a software reset of the transmitter and of the receiver (except the initial node
configuration after a hardware reset). (See
