I ran the following code:

        IO_CLR(LED_PORT, LED_TMR0 | LED_TMR1 | LED_TMR2);        //led_tmr0/1/2 driven to low
        IO_OUT(LED_DDR, LED_TMR0 | LED_TMR1 | LED_TMR2);        //led_tmr0/1/2 as output

        while(1)
                continue;
}

{

                {T0IF=0;

        if (RBIE&RBIF)//partB int need scan key  
                {RBIF=0;
        }
  
        if (TMR1IE&TMR1IF)//ccp INT  read perid
                {TMR1IF=0;
                IO_FLP(LED_PORT, LED_TMR1);                //flip led_tmr1
        }

        if (TMR2IE&TMR2IF)// PWM TIME INT    CHANGE DUTY
                {TMR2IE=0;                                                 //should reset the flag, not the interrupt enabling bit
                IO_FLP(LED_PORT, LED_TMR2);                //flip led_tmr2
        }
}
==========end code=============

it has three indicators, portc.0, portc.1, and portc.2 (on a 16F886), designated as tmr0/1/2 interrupt indicators: when tmr0 interrupt is serviced, LED_TMR0 (portc.0) is flip'd, and so on and so forth.

when I ran the code, the only thing flip'd is portc.0 (=LED_TMR0). that means the only interrupt service being executed is the one related to T0IF, as expected.
