Problem with LPC2103

Hi
I have written a simple code for lpc2103 to starting use of that, But this simple program dose not work after downloading on chip via J-LINK V.8 . When I debug the program, it stymies in PLL what for lock loop in startup code.

Please help me to solve this problem.

This is the code I have written .

core: LPC2103
Xtal frequency: 12MHz
MSEL:5
PSEL:2

code:


int main (void)
{
        IODIR=(1<<18);
        while(1)
        {
        IOSET=(1<<18);
        delay_ms(15);
        IOCLR=(1<<18);
        delay_ms(15);
        }
}

The program stop here:

;  Wait until PLL Locked
PLL_Loop       LDR     R3, [R0, #PLLSTAT_OFS]
               ANDS    R3, R3, #PLLSTAT_PLOCK
               BEQ     PLL_Loop
