80515 keil simulator don't trigger timer2 interrupt.

and you think it more likely that this is a fault in the Keil simulator than a fault in your code...?

void Timer2_Init(void)
{ T2CON = (T2CON & 0xFC); //stop timer2 TF2 = 0; //clear overflow flag TH2 = 0x4D; TL2 = 0xE0; ET2 = 1; //open timer2 interrupt T2CON = (T2CON & 0xFC) | 0x01; //start timer2
}

void Timer2_Isr(void) interrupt 5
{ Timer2_Init(); P0 = P0 ^ 0xFF;

void main(void)
{ EAL = 1; //open all interrupt Timer2_Init(); while(1) { ; }
}

Is that code 80515 keil simulator don't trigger timer2 interrupt.

void Timer2_Init(void)
{
    T2CON = (T2CON & 0xFC);       /*stop timer2*/
    TF2 = 0;  /*clear overflow flag*/
    TH2 = 0x4D;
    TL2 = 0xE0;
    ET2 = 1;  /*open timer2 interrupt*/
    T2CON = (T2CON & 0xFC) | 0x01; /*start timer2*/
}

void Timer2_Isr(void) interrupt 5
{
    Timer2_Init();
    P0 = P0 ^ 0xFF;
}

void main(void)
{
    EAL = 1; /*open all interrupt*/
    Timer2_Init();
    while(1)
    {
        ;
    }
}

EAL = 1; /*open all interrupt*/
what is 'EAL', never head of it in C51
