The timer with external interrupt issue.....

When use the timer, The external interrupts not work.........


stimer_t timer1; // Timer1

void.....(){
    timer1.handle.Instance = TIM1;
    TimerPulseInit(&timer1, 417, 0, IsrTim1);
    .
    .
    .
    pinMode(PA1, INPUT);
    attachInterrupt(PA1, rxPinChanged, CHANGE);
}

The timer interrupt working, But the external interrupts no work.
