External memory

hello,
i've declared an external memory mapped at address 8000H, and load data into it :

unsigned char xdata xdisp[15][24] _at_ 0x8000;
unsigned char i;
for (i = 0; i < 16; i++) {
   xdisp[i][0] = i;
   xdisp[i][1] = i + 1;
   xdisp[i][2] = i + 2;
   xdisp[i][3] = i + 3;
   xdisp[i][4] = i + 4;
   xdisp[i][5] = i + 5;
 }

for (i = 0; i < 16; i++) {
  P1 = xdisp[i][0];
  }

the result in P1 is the address of xdisp[i][0] and not the value in it.
how can i use a pointer or something else to recieve the values.

thanks
