function AVRUARTSetup(mode, baudrate, stopbits, parity)
// Function to Setup Serial Communication i.e UART or USART in ATmega16.
// Description
//        This function Setup the UART or USART for Serial Communicaion between ATmega16 
//        and different micro controllers or between ATmega16 and Computer.   
// 
// Parameters
//     mode : 
//           0 for Asynchronous Normal mode
//           1 for Asynchronous Double Speed mode
//           2 for Synchronous mode
//    
//     baudrate : Enter one of the following available baudrates
//                2400 , 4800 , 9600 , 14400 , 19200 , 28800 , 38400 , 57600 ,
//                768000 , 115200 , 230400 , 250000 , 1000000 .
//
//     stopbits : 
//               0 for one stopbit
//               1 for two stopbits
//
//     parity : 
//             0 for parity disabled
//             1 for even parity    
//             2 for odd parity
// 
//Examples
//     AVRUARTSetup(0,9600,0,0); //This function will enable UART Communication for ATmega16
//                                 with 9600 as baudrate,one stop bit and parity disabled

// This is curretly dummy function. It provides no functionality but is required 
// for providing support for generating C code for AVR.
