about cc2430 xdata memory process

I would like to use externel memory in CC2430 board.
I found an example named 'HalFlashP'. And I can see
uint8_t_xdata use in 'HalFlashP.nc'
like this --> uint8_t_xdata eraseFunctionBuffer[] =

But I don't apllied to my work.
What is 'xdata' memory associated with code?
I cannot find 'xdata'

I added 'typedef unsigned char uint8_t_xdata; --> keil_stdint.h
in C:\cygwin\opt\tinyos-2.x\tos\chips\mcs51

but, It caused compile error
What is the best way to solve this problem?
Please help me~
