You would need to connect an Analog voltage line to the VCC at the proper voltage levels. Then enable that line and sample it on each transmission.

So i have  to connect analog pin to vcc or simply enable to adc(2) and give adc input. Pls specify  i didn't  get your explanation.
In order to sample an Analog voltage, there are a few things you must do.

First, you must connect the desired voltage to the ADC pin at the proper voltage level. That is, you can't connect a 3V ADC line to a ADC pin that only accepts 1.2V Max. You would have to put a buffer circuit  with a level shifter in first.

Next, you would need to enable the ADC line on the processor. In this case ADC2 would need to be set to ADC.
