May be your device(RTL8019as) is not properly reset.

Make sure that it was reset completely.

then after if you not get possitive result make sure your Microcontrollers Port pins was configure in correct direction.

may be due to multiplex functionality of ports effect RTL8019as data or address lines.

After making sure all these things if you not get result then post your READ,WRITE and intiallisation code.
