hello frens,
   
   
  In Atmegax Datasheet, there mentioned about selection b/w  UBRRH  n UCSRC , which share common mem address.
   
  If i try to set baud rate first by selecting UBRRH with URSEL bit 0,
  n after that set frame format in UCSRC with URSEL bit 1, it is not working.
   
  but, if set frame format first in UCSRC without bothering about URSEL,
  n then baud rate settings in UBRRH, its working fine!
   
  how it is possible?
