    Problem of Pins Input

      On my own breadboard[Cy8C3246AXA], GPIO Read has a problem.   
      It is a 4bit program Sw, connect to P5[4]-P5[7]   
      Pins driive mode is Resistive pull up, initial:HIgh, Max voltage:5V   
      If program digit is ONE, port register might be 0xE0.   
      Actually, measured voltage is 0V,0,0,5V   
      But always 0x00 was red, whichever program digit is.   
      I had attached the project.   
      Any suggestions?
