Forum Post: RE: Apply 3.3 V on GPIO get automatically 1.2V on AVCC and 2.1V on DVCC

Hi Mukesh, Just to clarify, you are connecting the same 3V battery to AVCC and DVCC? Additionally, you have a separate 10k pull-up going from P2.0 and P2.1 to the 3V battery? Is anything else connected to P2.0 and P2.1? Thanks, Mitchell
