EUSART/AUSART: Enhanced/Addressable Universal Asynchronous Receiver Transceiver
The Enhanced/Addressable Universal Asynchronous Receiver Transceiver (EUSART/AUSART) is a peripheral for handling serial I/O communications. It contains all the clock generators, shift registers, and data buffers necessary to perform an input or output serial data transfer independent of the main program execution. The EUSART, also known as a Serial Communications Interface (SCI), can be configured as a full-duplex asynchronous system or half-duplex synchronous system.
