+function AVRADCSetup(prescalar,adc_ref)
+// Function to initialise ADC of AVR
+//
+// Calling Sequence
+//     AVRSetupADC(uint8 prescalar, uint8 adc_ref)
+//
+// Parameters
+//     prescalar: prescalar to be used for generating ADC clock (0-7)
+//     adc_ref	: reference voltage to be used for ADC conversion
+//              0 -> Voltage on VREF pin
+//              1 -> Voltage on AVCC pin
+//              2 -> Internal 2.56 reference voltage       
+//
+// Description
+//     This function initialises ADc of AVR with given parameters. 'prescalar' is 
+//     needed for deciding ADC clock. ADC clock should be between 50KHz and 200KHz
+//     and it given as (MCU clock/2^prescalar). Select appropriate prescalar depending
+//     on MCU clock. 'adc_ref' selects one of the available reference voltage sources
+//     available
+// Examples
+//     AVRADCSetup(128,0)

+// This is curretly dummy function. It provides no functionality but is required 
+// for providing support for generating C code for AVR.
