/* MODULE Bulid_option_8367 */
//The example is developed under CW8.0 and 56F8367EVM
//The code demo how to define an array rather than data pointer and allocated 
//the array to a specific address which is configured in CPU bean. user use /CS2 to access
//the space
//Result: connect CS2 (pin7 of J6 in 56F8367EVM) to oscilloscope, user can see /CS2 toggle
//in main.c
//user should write the code:
/***********************************************************/
//#pragma define_section mysection ".mysection.data" RW
/* 2. Specify the data to be put into the section. */
//#pragma section mysection begin
//unsigned int array[0x200];
//#pragma section mysection end
//in link command file,define
  //      .xData1  (RW) : ORIGIN = 0x00010000, LENGTH = 0x00080000
  //the above line is generated automatically
  
 //     .ApplDat:
 //      {
 //       * (.mysection.data)
 //       }> .xData1
/****************************************************************/

//user should configure  CS2 module and External memory module in "CPU
//properties" in CPU bean
//secondly, user should configure the "build option" in CPU bean
