Is there any thing wrong in reading the datasheets of the controllers or basic concepts of Embedded Prog. before posting??????

Both the requirements are different... what has IRQ to do with setting baud rate.. correct if i am wrong....

Study and understand IRQ handlers.. It has vectored and non vectored slots .. which understands the request type and configures the IRQ register....

Read the pdf of the controller you are using for more details....

Even setting the baud rate will be explained there
