     In my project,I use internal temperature sensor and two different ADC transfers of ADuC7023.The calling sequence: first is internal temperature sensor,second is ADC0,the laset one is ADC4.I found such a phenomenon.When I just use internal temperature sensor,the result of tempterature is steabily.But when I enable the other two ADC transfers ,the result of temperature will have a big change point every few minutes.

The attached file is my relevant program.



This is the tempature chating



So I do not understand the reason!
