Function
Note 1: Set the VREFON bit to 1 before setting the ADS bit in the ADMOD0 to start a conversion.
Note 2: The AN3 pin is shared with the ADTRG pin. Therefore, when the external conversion trigger
input ( ADTRG ) is enabled (i.e., when ADMOD1.ADTRGE = 1), the ADCH[2:0] field must not be
programmed to 011.
