+function AVRTimerSetup(timer,prescaler,clock_source)
+//Function to setup Timers in ATmega16
+//Descrpition:
+//      This function tells the micro controller which clock source you will be using.
+//      The timer value and prescaler value passed in this function setup the timer as per
+//      your requirement.
+//
+//Parameters:
+//     timer : It is an integer value. 
+//             0 to setup timer0
+//             1 to setup timer1
+//             2 to setup timer2   
+//     prescaler : It is an integer value.
+//                 1 for no prescaling i.e clock will run at max 16Hz frequency
+//                 8 for prescaling clock by 8 i.e new clock frequency will be (clk/8)
+//                 64 for prescaling clock by 64 i.e new clock frequency will be (clk/64)
+//                 256 for prescaling clock by 256 i.e new clock frequency will be (clk/256)
+//                 1024 for prescaling clock by 1024 i.e new clock frequency will be (clk/1024)
+//     clock_source : It is an integer value.
+//                    0 if you are using internal clock source       
+//                    1 if you are using external clock source
+//Example
+//    AVRTimerSetup(0,64,0);  //This function will select timer0 with timer running as per
+//                            internal clock source and prescaled by 64.     
+//

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