The SCI/LIN module contains the core SCI block with added sub-blocks to support LIN protocol.
The three major components of the SCI Module are:
The SCI receiver and transmitter are double-buffered, and each has a separate enable and interrupt bits. The receiver and transmitter can each be operated independently or simultaneously in full duplex mode.
To maintain data integrity, the SCI checks the data the SCI receives for breaks, parity, overrun, and framing errors. The bit rate (baud) is programmable to over 16 million different rates through a 24-bit baud-select register. Figure 37-1 shows the detailed SCI block diagram.
The SCI/LIN module is based on the standalone SCI with the addition of an error detector (parity calculator, checksum calculator, and bit monitor), a mask filter, a synchronizer, and a multibuffered receiver and transmitter. The SCI interface, the DMA control sub-blocks and the baud generator are modified as part of the hardware enhancements for LIN compatibility. Figure 37-2 shows the SCI/LIN block diagram.
