    MBR3, Pull down on I2C line



      I would like to check the reason why MBR3 require pulled-up on I2C line if the pins is unsed.

      Basically, I2C should be used by pulled-up but if I2C is not used and does not connect to anything device, MBR3 is not controlled ever after even if MBR3 enter stard condition. So I think we can be pulled-down on I2C line.


      Please let me know the reason MBR3 need pulled-up.


      Best regards,
