Greetings all!
I'm a bit confused on the interrupt vector code for catching interrupts on Timer A0 when using both the "capture" and "overflow" interrupts. When I just use the "capture" interrupt (which is driven by a PPS signal from a GPS unit), I use the following interrupt code:
#pragma vector=TIMER0_A0_VECTOR
__interrupt void TIMERA0_ISR (void)
{
P1OUT = P1OUT ^ 0b01000000; //Toggle green LED every second, which is driven by PPS signal
counter_flag++;
}
Now, I want to add a second interrupt to count the number of times TA0R overflows before the next PPS signal.
Do I use the same interrupt function as above, and simply add a switch(TA0IV) inside the interrupt function to determine which interrupt (capture or overflow) occurred?
OR, do I add a second interrupt function, and if so, what would the pragma vector statement be?
