All 3.3 V outputs require pull-up resistors. All fast 1.8 V outputs require pull-up resistors. The value of the pull-up resistors depends on the signal frequency.

Hi Clemens

All these pins are GPIO only . Still we need pull up on 3.3V but on 1.8 it is not required . Please confirm if my understanding is correct.

Yes. See section 5.2 of Voltage-Level Translation With the LSF Family.
