   <title>Description</title>
   <para>
Each Micro controller has PWM output pins which can generate varying voltage
from 0V-5V.This function Sets the duty cycle of output PWM signal.Also this function
decides the Top Vale of TCNT1 and the output pin to output PWM signal.
   </para>
   <para>
This is curretly dummy function. It provides no functionality but is required
for providing support for generating C code for AVR.
   </para>
   <para>
Example
AVRPWM1SetDuty(0,50,40000); //This function will produce PWM signal of 50% duty cycle on OC1A pin and TCNT1 will reset at 40000 instead at 65535.
</para>
