Resolved! Can i interface two different analog inputs to single pin(which is having two different ADC channels assigned ) of multi mode ADC in the STM32f205ZCCTTR. Can i scan those two with help of multimode ADC of STM32.?

If can, please share the physical connection diagram (two Analog voltage sources to single pin micro controller ) and sample code for that.
