This is a known problem. The datasheet should be updated with this errata in Creator 3.3 SP2.
The reason for this is, "For PSoC 4100 / PSoC 4200 devices I2C pins output enable is assigned to 0 to make High-Z state when I2C device does not drive the bus. This behavior suppresses usage of internal pull-ups ".
Thanks a lot for your reply. I tried to do it by various ways without a success, so now I know that I should cancel further attempts to achieve the feature.
