Please send me the solution

Hi all. I use ARM LPC2148 for my project and i use Keil uVision4.

µVision V4.60.0.0

Tool Version Numbers:
Toolchain: MDK-Lite Version: 4.60.0.0
Toolchain Path: C:\Keil\ARM\ARMCC\bin\
C Compiler: Armcc.Exe
Assembler: Armasm.Exe V5.02.0.28

I have a problem with interrupt handler irq. I write the following code in language c:

#include <lpc214x.h>

void tc0(void)__irq;
unsigned i = 0;
void main(void)
{

PLL0CFG=0x24; //Multipler and divider setup PLL0CON=0x01; //Enable PLL PLL0FEED=0xAA; //Feed sequence PLL0FEED=0x55; while(!(PLL0STAT & 0x0400)) ; //is locked? PLL0CON=0x03; //Connect PLL after PLL is locked PLL0FEED=0xAA; //Feed sequence PLL0FEED=0x55; VPBDIV=0x01;

VICIntSelect = 0x00;

VICVectAddr0 = (unsigned long)tc0; VICVectCntl0 = 0x20 | 4;

VICIntEnable = 0x10;

T0MCR = 0x03; T0MR0 = 0x00003000; T0TCR = 0x01;

while(1) { //loop }
}

void tc0(void)__irq
{ i = 1; T0IR = 0x01; VICVectAddr = 0x00;
}
