如何将533程序修改应用到518

原533的程序如下

#include <cdefBF533.h>
#include <sys\exception.h>
#define pDEVICE_OE (volatile unsigned short *)0x20320000
#define pLED_DAT (volatile unsigned short *)0x20340000
EX_INTERRUPT_HANDLER(TIMER0_ISR);
void Set_PLL(unsigned int pmsel,unsigned int pssel)
{
unsigned int new_PLL_CTL;
*pPLL_DIV = pssel;
asm("ssync;");
new_PLL_CTL = (pmsel & 0x3f) << 9;  
*pSIC_IWR |= 0xffffffff;
if (new_PLL_CTL != *pPLL_CTL)
{
  *pPLL_CTL = new_PLL_CTL;
  asm("ssync;");
  asm("idle;");
}
}
void Init_EBIU(void)
{
*pEBIU_AMBCTL0 = 0x7bb07bb0;
*pEBIU_AMBCTL1 = 0xffc07bb0;
*pEBIU_AMGCTL = 0x000f;
}
void Init_SDRAM(void)
{
*pEBIU_SDRRC = 0x00000817;
*pEBIU_SDBCTL = 0x00000013;
*pEBIU_SDGCTL = 0x0091998d;
ssync();
}
void Init_Timers(void)
{
*pTIMER0_CONFIG  = 0x0019;
*pTIMER0_PERIOD  = 0x00800000;
*pTIMER0_WIDTH  = 0x00400000;
*pTIMER_ENABLE  = 0x0001;
}

void Init_Interrupts(void)
{
*pSIC_IAR0 = 0xffffffff;
*pSIC_IAR1 = 0xffffffff;
*pSIC_IAR2 = 0xfffffff4;    
register_handler(ik_ivg11, TIMER0_ISR);  
*pSIC_IMASK = 0x00010000;
}

EX_INTERRUPT_HANDLER(TIMER0_ISR)
{
*pTIMER_STATUS = 0x0001;
printf("timer0 interrupt !\n");
}

void main(void)
{
Set_PLL(16,3);
    Init_EBIU();
    Init_SDRAM();
Init_Timers();
    Init_Interrupts();
    while(1);
}

程序原封不动写入PROJECT，选用518板子去试验，build file  和 rebuild project都没有问题，但是出现感觉进入不了中断，没有出现timer0 interrupt !    求高人帮助，谢谢！！

Andy哥，说好的Blackin移植专题讲解视频呢？赶紧那
