Connecting an Analog Signal on P0[x] to an ADC

Question: How do I connect a signal from and analog input pin on Port0 to an ADC?

 

Answer:

An ADC uses an SC Block and hence can only be placed on Row1 or Row2 in the analog blocks. These blocks do not have a direct access to the Analog Column Input muxes that connect to the analog input pins of Port0.  To connect the input pins on Port0 to the ADC, place a PGA in the CT block of the corresponding (or adjacent) analog column, set the gain of PGA to 1 (or any desired value), connect the Port0 pin to the input of the PGA and connect the output of the PGA to the input of the ADC.
