      Hi

      i want to configure a pin as both input and output, such emulate SDA of i2c master,  what driver mode should i use to make it work ?

      i tried strong driver/ pull up/down, found output works fine but input can't read right value in strong driver mode,

      and in pull up/down, output can't driver right voltage.

       

      appreciate your help and sharing your experience, thanks.
