 -  Specifically designed for the xplain board, other uses could be made by adjusting uart_soft_conf.h
 -  replacing the port, pin and timer assignments. Also relies on and external interupt to detect the low
 -  level of the start bit, in this case INT0.
 -  Always configured to 9600baud. Can be changed by setting the BITLENGTH define to F_CPU/(desired baud)
 -  code may need optimising when getting any faster to sample the bit in the correct place. No 
 -  compensation has been made for the response time of the int routine.
 -
 -  Note: Configured to use 16bit timers.
