<div class="refsection"><h3 class="title">Description</h3>
<p class="para">Every Micro controller has PWM pins which can generate varying voltages
from 0V-5V.This function helps to use OC1A or OC1B pin to produces required
output waveform by setting the waveform mode and otput mode.</p>
<p class="para">waveform_mode can take values-
<ul class="itemizedlist"><li><p class="para">0 -> for Phase correct PWM Mode</p></li>
<li><p class="para">1 -> for Fast PWM Mode</p></li>
<li><p class="para">2 -> for CTC Mode</p></li></ul></p>
<p class="para">output_mode can take values-
<ul class="itemizedlist">For Phase correct PWM Mode:
<li><p class="para">0 for Clear OC1A or OC1B on compare match when up-counting. Set OC1A or OC1B on compare match when down-counting.</p></li>
<li><p class="para">1 for Set OC1A or OC1B on compare match when up-counting. Clear OC1A or OC1B on compare match when down-counting.</p></li>
For Fast PWM Mode:
<li><p class="para">0 for non-inverted output i.e Clear OC1A or OC1B on compare match, set OC1A or OC1B at BOTTOM.</p></li>
<li><p class="para">1 for inverted output i.e Set OC1A or OC1B on compare match, clear OC1A or OC1B at BOTTOM.</p></li>
For CTC Mode:
<li><p class="para">0 to Clear OC1A or OC1B on compare match</p></li>
<li><p class="para">1 to Set OC1A or OC1B on compare match</p></li>
<li><p class="para">2 to toggle OC1A or OC1B on compare match</p></li></ul></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
AVRPWM1Setup(2,0,0); //This function will select CTC mode and will clear OC1A or OC1B
on compare match.Also as defined the output will be produced at
0C1A pin.</p></div>
