<title>Description</title>
<para>
This function initialises ADc of AVR with given parameters. 'prescaler' is needed for deciding ADC clock. ADC clock should be between 50KHz and 200KHz and it given as (MCU clock/2^prescaler). Select appropriate prescaler depending on MCU clock. 'adc_ref' selects one of the available reference voltage sources available.
</para>
<para>
The adc_ref can take the following values-
<itemizedlist>
<listitem><para>0 -> Voltage on VREF pin</para></listitem>
<listitem><para>1 -> Voltage on AVCC pin</para></listitem>
<listitem><para>2 -> Internal 2.56 reference voltage</para></listitem>
</itemizedlist>
</para>
<para>
This is curretly dummy function. It provides no functionality but is required for providing support for generating C code for AVR.
