The Function Extension for the McBSP of TMS320C6000 Series DSP

Multi-channel Buffered Serial Port (McBSP) is a standard component of TMS320C6000 series DSP, and also is a kind of enhanced serial port. McBSP characterizes its good expansibility, and can be extended to various type of interface port. After the principle of McBSP is analyzed, the configuration method, operation mode and program routines are presented for configuring the McBSP as General Purpose Input Output (GPIO), Universal Asynchronous Receiver/Transmitter (UART) or Serial Peripheral Interface (SPI). Experiments show that every extended function of the McBSP works well in practical computer system.
