Whether a pin is 5V tolerant or not is due to the physical hardware of that pin - it is not configurable.

Hello
rakshith
,You may refer to table 'STM32F070xB/6 pin definitions' in the
to get the I/O structure.Khouloud.

See also section 6.3.14, 'I/O port characteristics' in the same document.

Your question, 'How to enable GPIO 5V tolerance' has been answered.
If your output is not driving to the expected level, that's a different question.
Suggest you mark this thread as answered, and start a new thread about your output drive problem.
But you will need to give a lot more detail for anyone to be able to help in that new thread:
