*
* @brief Interrupt UART library using the built-in UART with transmit and receive circular buffers.
*
* This library can be used to transmit and receive data through the built in UART.
*
* An 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_RX_BUFFER_SIZE and UART_TX_BUFFER_SIZE constants define
* the size of the circular buffers in bytes. Note that these constants must be a power of 2.
* You may need to adapt these constants to your target and your application by adding
* CDEFS += -DUART_RX_BUFFER_SIZE=nn -DUART_TX_BUFFER_SIZE=nn to your Makefile.
