Timer Interrupts for PIC18...

[sraiderk]

if I used the timer0 and timer1 interrupt, what is the result for the following condition. (for pic 18 series) .

Case 1: Both timer interrupt occurs at the same time.

Case 2: Timer0 interruptted , Then MCU execute the interrupt routine. At that point (when MCU execute the interrupt routine) Timer1 is interrupted.

Case 3: Timer0 interruptted. First code line in Timer0 interrupt routine is the "disable_interrupts(Timer1)" The last line in the Timer0 interrupt routine is the "enable_interrupts(Timer1)".

Timer0 interrupt routine()
{
disable_interrupts(Timer1);
....;
....;
x;
...;
...;
enable_interrupts(Timer1);
}

if the timer1 overflow occurs at x. the interrupt occurs or not after "enable_interrupts(Timer1)" code line for pasted overflow?
