高人们，帮我看看吧，为什么没有产生中断：
main.c文件：
#include /* common defines and macros */
#include /* derivative information */
#pragma LINK_INFO DERIVATIVE "mc9s12dg128b"
unsigned int time,count=0;
//time为小轮一圈的时间1表示0.0013653s 一圈4cm
unsigned int lasttime=0,thistime;
//lasttime为上次的计数器值，thistime为此次的计数器值
#pragma CODE_SEG __NEAR_SEG NON_BANKED
void interrupt 51 TIME4_ISR(void);
void interrupt 47 TIMEOF_ISR(void);
#pragma CODE_SEG __NEAR_SEG NON_BANKED
void interrupt 51 TIME4_ISR(void)
{
TFLG1_C4F = 1 ; //清中断标志位
//EnableInterrupts;
thistime=TC4;
time=count*4096+(thistime-lasttime)/16;
count=0;
/*if(thistime>lasttime)
time=thistime-lasttime;
else
time=0xffff-lasttime+thistime;
*/
//lasttime=thistime;
}
void interrupt 47 TIMEOF_ISR(void)
{
TFLG2_TOF = 1; //清定时器溢出标志位
count++;
}
void main()
{
PWMPOL=0XFF; //设置PWM脉冲以上升延开始
PWMCLK=0X20; //设置CLOCK SA作为PWM的时钟源
PWMPRCLK=0x04; //设置CLOCK A频率为bus clock/128
PWMCAE=0;
PWMSCLA=0x05; //设置CLOCK SA的频率
PWMSCLB=0;
PWMCTL=0;
PWMCNT5=0;
PWMPER5=0XFF; //设置PWM周期

PWME=0XFF;
PWME_PWME5=1;
EnableInterrupts;
TIOS=0X00;

while(1)
{
//PORTA=time;
}
}
