    I2C pull-up on CY8C4125PVI-482 ???

    user_397535303

      Hi, I cannot enable internal pull-ups on I2C pins in the above mentioned device. The same code works just fine in CYBLE-022001-00, which is also PSoC 4 based, you know.

         

          I2C_Start();
          I2C_scl_SetDriveMode(I2C_scl_DM_RES_UP);        // use internal pull-up I2C resistors
          I2C_sda_SetDriveMode(I2C_sda_DM_RES_UP);

         

      Question is, hence, how to do the same in 4100 series? The closest topic I found is this:

      However, a similar problem is not solved there.

         

      Also, are there any Hardware Errata-sheet documents?
