If the ports are pulled up/down, is there a problem connecting to power?

Latest Updated:03/24/2009

Question:

When the ports are pulled-up or pulled-down, is there any problem if connecting port to power supply directly?

Answer:

Since it is possible that an over-current or under-current condition may occur in the event that the input protection circuit is damaged due to unexpected situations (such as variation of power supply voltage etc.), please connect a resistor between the power supply line and the pin.
