 DESCRIPTION:
     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 variables define
     the buffer size in bytes. Note that these variables must be a
     power of 2.
 
+
 USAGE:
     Refere to the header file uart.h for a description of the routines.
     See also example test_uart.c.
