<p class="refpurpose">Function to Set Duty cycle of PWM Output generated by Timer1 at OC1A or OC1B pin.</p></div>
<div class="refsection"><h3 class="title">Parameters</h3>
<dl><dt><span class="term">ouput_pin:</span>
<dd><p class="para">integer, 0 (for OC1A) or 1 (for OC1B)</p></dd></dt>
<dt><span class="term">duty:</span>
<dd><p class="para">It holds an integer value from 0 to 100 which sets the percentage of time for which signal is active.</p></dd></dt>
<dt><span class="term">Top_Value:</span>
<dd><p class="para">It holds an integer value from 0 to 65535.This value sets the Top value of the counter TCNT1 i.e ICR.(for more info refer datasheet)</p></dd></dt></dl></div>
<div class="refsection"><h3 class="title">Description</h3>
<p class="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.</p>
<p class="para">This is curretly dummy function. It provides no functionality but is required
for providing support for generating C code for AVR.</p>
<p class="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.</p></div>
