Hello,

I can't understand why my timer0 can't count on my 80C52 :
It have to generate a frequency around 8kHz but the STOR don't switch up and down
I init the timer like this :

Timer0_init()
{
ET0 = 0;
TR0 = 0;
TMOD &= 0xF0;
TMOD |= 1;
TL0 = 115;
TH0 = 0;
TR0 = 1;
ET0 = 1;
}

and next my interrupt looks like this :

void ItTimer0(void) interrupt 1 using 2
{
EA = 0;
ET0 = 0;
STOR1 ^= 1;
TL0 = 115;
TH0 = 0;
ET0 = 1;
EA = 1;
}

I call Timer0_init in the main function

Thanks a lot if you can give me some hints
