function count = AVRGetTimerValue(timer)
// Function to get timer count
//
// Parameters
//     timer : timer whose current count is to be returned 
//             0 for timer0
//             1 for timer1
//             2 for timer2
//              
// Description
//     This function returns the count value of a desired timer.By knowing the count value certain interrupt action can be taken.
//
//     Timer can take the following values
//     <itemizedlist>
//     <listitem><para>0   -> for timer0</para></listitem>
//     <listitem><para>1   -> for timer1</para></listitem>
//     <listitem><para>2   -> for timer2</para></listitem>
//     </itemizedlist>
//
// This is curretly dummy function. It provides no functionality but is required 
// for providing support for generating C code for AVR.
//
// Examples
//     AVRGetTimerValue(0);   //returns present count of the TCNT0 counter
// See also
//     AVRTimerSetup
