Solution:

There is no recommended value for pull-up resistor on the user I/O pin, as it depends on the purpose of using the pin.

If the pullup is to avoid keeping a pin floating, then any pull-up value is fine unless power is a requirement. In such case, a higher resistor value is required for pullup. Generally, its recommended 4.7K pull-up resistor value.
