WebUSART (Universal Synchronous Asynchronous Receiver Transmitter) which transfers the data bits serially. Using USART, we can communicate with the PC and serial UART devices like GSM module, GPS, etc. WebAn interrupt is generated when the UART has finished transmitting or receiving a byte. The interrupt handling routines use circular buffers for buffering received and transmitted data. The UART_RXn_BUFFER_SIZE and UART_TXn_BUFFER_SIZE constants define the size of the circular buffers in bytes. Note that these constants must be a power of 2.
