+function AVRPWM2SetDuty(duty)
+//Function to Set Duty cycle of PWM Output generated by Timer2 at OC2 pin.    
+//Description
+//      Each Micro controller has PWM output pins which can generate varying voltage
+//      from 0V-5V.In this function by varying the duty cycle, varying voltage can be 
+//      produced.
+//
+//Parameters
+//	duty : It holds an integer value from 0 to 100 which sets the percentage
+//             of time for which signal is active.
+//
+//Example
+//      AVRPWM2SetDuty(50); //Produces 2.5V at OC2 pin
+//      AVRPWM2SetDuty(0); //Produces 0V at OC2 pin
+//

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