VicIntEnable Register of LPC2148

Hi.. I urgently want to know the configuration of the VicIntEnable Register of LPC2148. I've searched everywhere but in vain. Can someone pls help? Need it for my final year project.

Thank you. Muito obrigada:)
 
Thanks alot Atom. I found the register configuration but the use of VICIntEnClr register to disable the UART1 interrupt still does not work. Could you pls check my code and tell me why?
Thanks.

Code:
#include "LPC214x.h"

void init(void);
extern unsigned char at[]="ATE0";
extern unsigned char cmgf[]="AT+CMGF=1";	                        //Text format in GSM modem
extern unsigned char cmgs[]="AT+CMGS=\"+917875252763\"";           	//Mobile number to which the msg is sent
extern unsigned char msg[]="Heya:P";								


void senduart1(unsigned char a)					//sends a byte through U1
{
U1THR=a;
while(U1LSR!=0x60);
}

void sendstring(unsigned char *p)			 //Sends a string of data through UART1
{
while(1)
{
if(*p=='\0') break;
senduart1(*p++);
}
}

void delaygsm()							  //delay function
{
int i,c=0;
for(i=0;i<4000000;i++)
{
c++;
}
}


int main()
{  VICIntEnClr=0x00000080;
PINSEL0=0x00050005;			//initialized U0 and U1 as UART and not GPIO
PINSEL1 = 0x00000000;
PINSEL2 = 0x00000000;
IO1DIR = 0xFFFFFFFF;

init();

sendstring(at);
senduart1(0x0D);										// equivalent of 
senduart1(0x0A);
										//	 enter key
delaygsm();

IO1SET = 0x00010000;
	
sendstring(cmgf);
senduart1(0x0D);										// equivalent of 
senduart1(0x0A);									//	 enter key
delaygsm();


IO1SET = 0x00020000;
sendstring(cmgs);
senduart1(0x0D);
senduart1(0x0A);
delaygsm();

IO1SET = 0x00040000;


sendstring(msg);
senduart1(0x1A);
IO1SET = 0x00080000;
delaygsm();

senduart1(0x1A);
IO1CLR=	0x000F0000;
}


void init()
{

U1LCR=0x83; //8-N-1, enable divisors
U1DLL=0x62; //9600 baud (9615)
U1DLM=0x00;
U1LCR=0x03; //8-N-1, disable divisors
U1FCR=0x07;
 
}
