<div class="refsection"><h3 class="title">Description</h3>
<p class="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.</p>
<p class="para">The adc_ref can take the following values-
<ul class="itemizedlist"><li><p class="para">0 -> Voltage on VREF pin</p></li>
<li><p class="para">1 -> Voltage on AVCC pin</p></li>
<li><p class="para">2 -> Internal 2.56 reference voltage</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>
