PORT Registers initialization to safe state

     I am working on the MCU MC9S08SG16 (28PIN).

     I need to initialize the IO ports to a safe state.

     As per the data sheet, it is safe to initialize the UN connected pins as OUTPUT.

     But in my case all pins are connected only.


     Suppose for safe state analysys, if a Input device is connected to a Port pin which is configured as OUTPUT,

     Then is there any damage to the io pin ?


     Also suggest me the better ports configuration for the safety critical applications.
