PLL using LPC2148(ARM)

PLL0 Code: 

Ex-

#include<lpc214x.h>
#define PLLE 0
#define PLLC 1
#define PLOCK 10
int main()
{
 PLL0CFG=0x25;
 PLL0CON=PLL0CON|(1<<PLLE);
 PLL0FEED=0xAA;
 PLL0FEED=0x55;
 //PLL0CON=PLL0CON|(1<<PLLC);
 while( (PLL0STAT & (1<<PLOCK))==0);
 PLL0CON=PLL0CON|3;
 PLL0FEED=0xAA;
 PLL0FEED=0x55;   
 VPBDIV=0x00;
return 0;
}
