    Very simple question on SAR ADC example (PSOC 4 Lab 4)

    user_1409605

      For the SAR ADC example, where an ADC is used with an analog input pin, just a simple question:

         

      Why do we have to assign a physical pin to both the ADC and the analog input pin?  Doesn't the ADC "not" need a pin, because we are connecting it to the analog pin?  It would seem to me that the connection between the ADC and the pin would be internal...

      Edit: just for clarity sake, here's what the lab 4 manual says:

         

      map the “ADC_SAR_Seq_1:Bypass” pin to P1[7], and “Pin_1” to P2[0]
