It depends on the target device family and how you're implementing the controller: soft or hard?  If it's hardened, like in newer devices, you may not even be able to use the other pins in the I/O bank as GPIO.  What's your target device?

Hi XG_Kang,

 

May I know how you're implementing the controller, is it soft or hard?
As mentioned above, if it is hard, you may not be able to use other pins in that I/O bank as GPIO
