Can i use half of Address pins of EMIF as GPIOs in Delfino F28375S

hii,

I am Working on Delfino F28375S C28x and i am trying to interfacing with External asynchronous memory to the controller(mean EMIF), here i am using 8-pins (address pins) out of 22 pins to access the memory may i use remaining address pins as GPIOs.

If i use remaining as GPIOs is, it may effect accessing the memory or it may disturb the GPIOs.

Note: Project is in schematic level.

Thanks in Advance.
