function AVRPWM2Setup(waveform_mode,output_mode)
//Function to Setup OC2 pin for required PWM mode
//
//Parameters
//	waveform_mode: integer, from 0 to 2
//      output_mode: integer, from 0 to 1 (or 2) depending on the waveform_mode
//    
//Description
//	Every Micro controller has PWM pins which can generate varying voltages
//	from 0V-5V.This function helps to use OC2 pin to produces required 
//	output waveform by setting the waveform mode and otput mode.
//
//	waveform_mode can take values-
//	<itemizedlist>
//      <listitem><para>0   -> for Phase correct PWM Mode</para></listitem>
//      <listitem><para>1   -> for Fast PWM Mode</para></listitem>
//      <listitem><para>2   -> for CTC Mode</para></listitem>
//      </itemizedlist>
//
//	output_mode can take values-
//      <itemizedlist>
//      For Phase correct PWM Mode:
//	<listitem><para>0 for Clear OC2 on compare match when up-counting. Set OC2 on compare match when down-counting.</para></listitem>
//	<listitem><para>1 for Set OC2 on compare match when up-counting. Clear OC2 on compare match when down-counting.</para></listitem>
//      For Fast PWM Mode:
//	<listitem><para>0 for non-inverted output i.e Clear OC2 on compare match, set OC2 at BOTTOM.</para></listitem>
//	<listitem><para>1 for inverted output i.e Set OC2 on compare match, clear OC2 at BOTTOM.</para></listitem>
//      For CTC Mode:
//	<listitem><para>0 to Clear OC2 on compare match</para></listitem>
//	<listitem><para>1 to Set OC2 on compare match</para></listitem>
//	<listitem><para>2 to toggle OC2 on compare match</para></listitem>
//      </itemizedlist>
//
// This is curretly dummy function. It provides no functionality but is required 
// for providing support for generating C code for AVR.
//
//Example
//    AVRPWM2Setup(2,0);     //This function will select CTC waveform mode and will clear OC2 on    
//                           compare match
