CCD采集程序放在中断里 2个PIT问题

#pragma CODE_SEG __NEAR_SEG NON_BANKED
void interrupt VectorNumber_Vpit0  PIT0_ISR(void)
{

   PITTF_PTF0=1;
//
PITCE_PCE1=0;
   anglecalculate();

   Anglecontrol();
   motoroutput();
   motor_speed_out();
   speed_ce();

   num++;


   DirectionControl();
   DirectionControlOutput();
//  OutData[3]=a;
   // OutPut_Data();

   if(num==10)
   {

   speedcontrol() ;
   speedcontrolout();
   num=0;
   speed_right=0,speed_left=0;
   }
// PITCE_PCE1=1;
}
#pragma CODE_SEG DEFAULT

#pragma CODE_SEG __NEAR_SEG NON_BANKED
void interrupt VectorNumber_Vpit1  PIT1_ISR(void)
{  PITTF_PTF1=1;

EnableInterrupts;
  // PORTK_PK5=1;
TSL1401_GetLine(gPixel);

}
#pragma CODE_SEG DEFAULT
这样中断嵌套的时候为什么会对直立有影响  CCD曝光为30ms  当在PIT0把PIT1中断关掉的话就不能采集  求大神解释
