performing adc

when iam writing the program for adc it is executed. But iam trying to do in debug session it showing disassembly.
plz help me where I can do the mistake.my program is

#include <LPC214X.H>
#include <stdio.h>
void init_UART0(void);
void init_ADC0_1(void);
void ADC_read(void);
int main()
{ int value;
VPBDIV=0X02;
init_UART0();
init_ADC0_1();
{ U0THR=value;
printf("adcvalue=%d",value);
} }

void init_ADC0_1(void)
{

PINSEL1=0X01000000;
PCONP=0X00001008;
AD0CR=0X00000001;
AD0CR=0X00000600;
AD0CR=0X00070000;
AD0CR=0X00100000;
} void ADC_read(void)
{ int value=0;
AD0CR=0X01000000;
while(value&(0x80000000)==0);
value=AD0GDR;
value=((AD0GDR>>6)); value&=0x3ff;
AD0CR=~(0X01000000);
} void init_UART0(void)
{ PINSEL0=0X00000005;
U0LCR=0X00000083;
U0DLL=0X000000c3;
U0LCR=0X00000003;
U0FCR=0X00000007;
}
