Hi

I didn't find the specific instruction on how to use  external channels  of ADC.

  I've known that there are three decode signals MA0,MA1 and MA2 for a multiplexer, but will the decode signals be generated automatically?  How should I configure this module if I want to use ADC external channels with a multiplexer?

 

Thank you!

MA signals are generated automatically when particular PINs are configured for this function

and your software will convert ADC channels 64-95. Understandably you will have to have use external multiplexers (up to four 8-to-1 MUXes).
