程序如下，LED灯没有变化

#include "STC8h.h"
#include "intrins.h"
typedef unsigned char u8;
typedef unsigned int u16;
sbit led=P1^1;
u16 num;
void GPIO_Init()
{
P1M0 = 0xFF;
P1M1 = 0xFF;
P5M0 = 0x00;
P5M1 = 0x00;
P3M0 = 0x00;
P3M1 = 0x04;
}

void STC8ADC_Init()
{
P_SW2 |= 0x80;
ADCTIM = 0x3f;
P_SW2 &= 0x7f;
ADCCFG = 0x00;
ADC_CONTR = 0x8A;
}

void ADC_Isr() interrupt 5
{
EADC = 1;
  ADC_CONTR |= 0x40;
  _nop_();
  _nop_();
while(  !(ADC_CONTR&0x20) );
  ADC_CONTR&= ~0x20;
  num=(ADC_RES<<8) | ADC_RESL;
}

void main()
{
   GPIO_Init();
STC8ADC_Init();
    EA=1;
led=1;
while(1)
{
if(num>300)
led=~led;
}}
