The following are the features of the SCI module:
- Standard universal asynchronous receiver-transmitter (UART) communication
- Supports full- or half-duplex operation
- Standard non-return to zero (NRZ) format
- Double-buffered receive and transmit functions in compatibility mode
- Supports two individually enabled interrupt lines: level 0 and level 1
- Configurable frame format of 3 to 13 bits per character based on the following:
- Data word length programmable from one to eight bits
- Additional address bit in address-bit mode
- Parity programmable for zero or one parity bit, odd or even parity
- Stop programmable for one or two stop bits
- Asynchronous communication mode
- Two multiprocessor communication formats allow communication between more than two devices
- Sleep mode is available to free CPU resources during multiprocessor communication and then wake up to receive an incoming message
- The 24-bit programmable baud rate supports 224 different baud rates provide high accuracy baud rate selection
- At 100MHz peripheral clock,
3.125Mbps is the maximum baud rate achievable
- Capability to use direct memory access (DMA) for transmit and receive data
- Five error flags and seven status flags provide detailed information regarding SCI events
- Two external pins: LINRX and LINTX
- Multibuffered receive and transmit units
Note:
The SCI/LIN module is functionally compatible with the C2000™ SCI modules, but not directly software compatible due to different register control structures.
The SCI/LIN module does not support UART hardware flow control. This feature can be implemented in software using a general-purpose I/O pin.
The SCI/LIN module does not support isosynchronous mode as there is no SCICLK pin.
