    I have 300Hz interfere when I dont route analog input to recommended pin

      Hi,

      I'm using the CY8C5868AXI-LP035.

      I routed pin 9 (p6[7]) to analog input of power monitor (I know it is not recommended analog input, but I didnt have place).

      Once I start the power monitor I measure with scope outside the device (on pin 9) the desired signal but the psoc also add a 300Hz "noise". It doesn't matter If I change any configuration of the power monitor, the problem remains.

      If I don't start the power monitor, or start the power monitor but dont assign pin 9 everything ok.

       

      Can you pls advise how can the device create a 300Hz interference?

       

      BR,

      Barak
