PSOC TRM explains that capsense uses two switches: one connects pin (sensor)  to AMUX bus, second connects tha same AMUX bus to idac or external resistor.

   

In my project I would like to do similar thing for analog hardware  mutiplexing.

   

I've found that digitally driven switch can be realized using pin module.

   

Is there a way to connect AMUXBUS to IDAC via internal switch without using pin resource.

In other words:

   

Is there a way to connect (switch) input pin to OPAMP module on whaterver clock signal "1"

   

and connect addtionally resitor or IDAC output on whatever clock signal "0"

   

 

   

This is what capsense is doing.
