Yes, during the selectmap configuration the Address pins A0-A25 toggle, but this must be taken care in your system during configuration. This is made a note in UG380.

are you facing any problem configuring from platform flash?

I used A4 as a switch signal. The signal must output low when power on and configration. Now it can not work correctly because the toggle. Can i set A4 to output low when configration?
