function AVRUARTSetup(mode, baudrate, stopbits, parity)
// Function to Setup Serial Communication i.e UART or USART in ATmega16.
// 
// Parameters
//     mode : integer, from 0 to 2
//     baudrate : Enter one of the following available baudrates (2400 , 4800 , 9600 , 14400 , 19200 , 28800 , 38400 , 57600 , 768000 , 115200 , 230400 , 250000 , 1000000)
//     stopbits : integer, (0 for one stopbit) or (1 for two stopbits)
//     parity : integer, from 0 to 2
// 
// Description
//        This function Setup the UART or USART for Serial Communicaion between ATmega16 
//        and different micro controllers or between ATmega16 and Computer.   
//
//	mode can take values:
//	<itemizedlist>
//      <listitem><para>0 for Asynchronous Normal mode</para></listitem>
//      <listitem><para>1 for Asynchronous Double Speed mode</para></listitem>
//      <listitem><para>2 for Synchronous mode</para></listitem>
//      </itemizedlist>
//
//	parity can take values:
//	<itemizedlist>
//      <listitem><para>0 for parity disabled</para></listitem>
//      <listitem><para>1 for even parity</para></listitem>
//      <listitem><para>2 for odd parity</para></listitem>
//      </itemizedlist>
//
// This is curretly dummy function. It provides no functionality but is required 
// for providing support for generating C code for AVR.
//
//Examples
//     AVRUARTSetup(0,9600,0,0); //This function will enable UART Communication for ATmega16
//                                 with 9600 as baudrate,one stop bit and parity disabled
