I am using MC9S12G in my development . I want to know that what would be the minimum current consumed by controller when only two port pins are used as output,first port pin is used as to trigger the watchdog and other is used as for LED on/off(Flashing) activity.

I tried with MCU STOP mode , current consumption goes low but watchdog triggering also not happening  in stop mode.

As per my understanding in STOP mode CPU does not runs.

 

Please suggest how much minimum current needed to perform the above activity and how we can achieve that.
