9-1 Synchronous Serial Port
Synchronous Serial Port
The ’C2xx devices have a synchronous serial port that provides direct
communication with serial devices such as codecs (coder/decoders) and
serial A/D converters. The serial port may also be used for intercommunication
between processors in multiprocessing applications.
The synchronous serial port offers these features:
- Two four-word-deep FIFO buffers
- Interrupts generated by the FIFO buffers
- A wide range of speeds of operation
- Burst and continuous modes of operation
For examples of program code for the synchronous serial port, see Appendix C,
Program Examples.
