Asynchronous Serial Port
Asynchronous Serial Port
The ’C2xx has an asynchronous serial port that can be used to transfer data
to and from other devices. The port has several important features:
-
Full-duplex transmit and receive operations at the maximum transfer rate
-
Data-word length of eight bits for both transmit and receive
-
Capability for using one or two stop bits
-
Double buffering in all modes to transmit and receive data
-
Adjustable baud rate of up to 250,000 10-bit characters per second
-
Automatic baud-rate detection logic
For examples of program code for the asynchronous serial port, see Appendix C,
Program Examples.
