TMS320F28388D: Pins characteristic change if set as GPIO or I2C ?

Part Number: TMS320F28388D

Hi team, 

Does the characteristic of the pins of the C2000 family (rising time ...) change if it is configured in GPIO or in I2C ? 

I have doubt after reading the SLVA689 document. 

Regards,

Geoffrey

    When GPIO pins are configured as I2C pins, then they are open drain IO. Rise time and fall time depends on the external pull and bus capacitance. Table below shows the maximum permissible rise time / fall time for standard / fast mode.

    Regards,
