急求，马上给分，还加分 我把程序下载进单片机，有一个灯一直闪，我没按按键也闪。也就是有一个中断没发生也闪，麻烦高手修改完发给我，谢谢！#include
#define uint unsigned int
#define uchar unsigned char
sbit LED=P0^0
sbit LED1=P0^1
void delay1ms (uint z)
{
uint x,y
for (x=zx>0x--)
for (y=110y>0y--)
}
void exter() interrupt 2
{
delay1ms(600)
LED=0
delay1ms(200)
LED=1
}
void exter0() interrupt 0
{
delay1ms(600)
LED1=0
delay1ms(200)
LED1=1
}
main()
{
EA=1//开总中断
EX1=1//开外部中断1
EX0=1//开外部中断0
IT1=0//外部中断边沿触发，下降沿触发
IT0=0//外部中断0边沿触发，下降沿触发
}
