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.
