7.6 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.
7.6.1 LIN Features
The following are features of the LIN module:
• Compatible to LIN 1.3, 2.0 and 2.1 protocols
