How to assign initial values in code memory with specific location?

I want to define some values in code memory with specific location. For example

code unsigned char MyArray[] _at_ 0xF000 = {0x01, 0x02};

After that, I can use "MyArray[0]" and "MyArray[1]" to access the memory at 0xF000 and 0xF001.
How can I achieve this?
