Local Interconnect Network Interface (LIN)

The SCI/LIN module can be programmed to work either as an SCI or as a LIN. The core of the module is

an SCI. The SCI’s hardware features are augmented to achieve LIN compatibility.

The SCI module is a universal asynchronous receiver-transmitter that implements the standard nonreturn

to zero format. The SCI can be used to communicate, for example, through an RS-232 port or over a K-

line.

The LIN standard is based on the SCI (UART) serial data link format. The communication concept is

single-master/multiple-slave with a message identification for multicast transmission between any network

nodes.
