求大神帮忙把下边的c语言的程序改成汇编实现

#include<reg52.h>
#include<intrins.h>
#define uint unsigned int
#define uchar unsigned char
sbit BE = P3 ^ 7;
void delay(void)
{
uchar i;
for(i = 143; i > 0; i--);
}
void main(void)
{
unsigned int j;
P0 = 0xff;
while (1)
{
for(j = 490; j > 0; j--)
{
BE = ~BE;
P0 = 0x7E;
delay();
delay();
}
for (j = 490; j > 0; j--)
{
BE = 1;
P0 = 0xff;
delay();
delay();
}
}
}
