   6:../avr-lib/drivers/uart/uart.c **** Hardware: any AVR with built-in UART,
20 
   7:../avr-lib/drivers/uart/uart.c ****           tested on AT90S8515 at 4 Mhz and ATmega at 1Mhz
21 
   8:../avr-lib/drivers/uart/uart.c ****
22 
   9:../avr-lib/drivers/uart/uart.c **** DESCRIPTION:
23 
  10:../avr-lib/drivers/uart/uart.c ****     An interrupt is generated when the UART has finished transmitting or
24 
  11:../avr-lib/drivers/uart/uart.c ****     receiving a byte. The interrupt handling routines use circular buffers
25 
  12:../avr-lib/drivers/uart/uart.c ****     for buffering received and transmitted data.
26 
  13:../avr-lib/drivers/uart/uart.c ****
27 
  14:../avr-lib/drivers/uart/uart.c ****     The UART_RX_BUFFER_SIZE and UART_TX_BUFFER_SIZE variables define
28 
  15:../avr-lib/drivers/uart/uart.c ****     the buffer size in bytes. Note that these variables must be a
29 
  16:../avr-lib/drivers/uart/uart.c ****     power of 2.
30 
  17:../avr-lib/drivers/uart/uart.c ****
31 
  18:../avr-lib/drivers/uart/uart.c **** USAGE:
32 
  19:../avr-lib/drivers/uart/uart.c ****     Refere to the header file uart.h for a description of the routines.
33 
  20:../avr-lib/drivers/uart/uart.c ****     See also example test_uart.c.
