STM32F401 FSMC

Hi all,
I enabled FSMC bus on STM32F4 series controller. When nothing is connected to the bus, and when I do a write followed by read, I am getting the same data that was written. Can anyone help me understand why this is happening? Should I not get 0xff ideally? Also is there a provision to enable pull-ups on the data bus? Thank you.
