/* Define GPIO Pin Data Input/Output. It could be used to control each I/O pin by pin address mapping.
   Example 1:

       PA0 = 1;

   It is used to set GPIO PA.0 to high;

   Example 2:

       if (PA0)
           PA0 = 0;

   If GPIO PA.0 pin status is high, then set GPIO PA.0 data output to low.
