Don't work Parallel Bus Mode

I bought a W5100S chip and built my own custom board with it. Schematics is an exact copy of the schematics provided by Wiznet. Interface Mode is selected by MOD [3: 0], I have selected “010X”: Parallel Bus Mode. I can’t read any of the registers. In accordance with section 7.4.2. I configured the interface and tried to read the register “MR” at 0x0000. Result 0x03.
I tried to read other registers, I always get the result 0x03. What could be the problem?
