Sharing pin for ADC and ACMP

Question asked by Eric Bryan on Jul 6, 2017

Using an MC9S08PA8VTG.  ACMP input and ADC input share pin 16.  Codewarrior balks at assigning both peripherals to the same pin.  I see nothing in the data sheet that says I can't and the application is pin limited  so I don't want to route the same signal to two pins.  I want the ACMP to monitor my incoming power so I can save my data if power is going down.  Customer also wants to measure the incoming power.  So:

 

1. Does the hardware allow these two functions to share a pin and operate simultaneously?

2. If yes, is there a way to make Codewarrior enable both?

 

Thanks for any assistance.
