Using the __at macro that is defined in the header file absacc.h allows you to locate variables to absolute addresses as shown below:

C Example:

＃i nclude 

const char MyText[] __at (0x1F00) = "TEXT AT ADDRESS 0x1F00";
int x __at (0x40003000);     // variable at address 0x40003000

Assembler Example:

In assembler files you may define the location using section names composed of |.ARM.__AT_|. The following example will locate a section to address 0xFFE0:

     AREA |.ARM.__AT_0xFFE0|, CODE, READONLY
