Interrupts

[Archangel]

OK lets beat this subject into shim stock . . . INTERRUPTS are TRIGGERED by hardware events, They are handled by software. Assembly will start working on the interrupt within 2 to 4 cycles of the Oscillater. PBP On Interrupt, puts a pointer on the stack, like it does with a subroutine, and executes it right after it finishes what it is doing.
Consider this:

start:
on interrupt goto Emergency<font color=red><b>_</b></font color>stop  ':D thanks mister_e
main:
PortB.3 = 1 ' motor runs for 1 minute, stops for 1 minute
pause 60000
PortB.1 = 0
Pause 60000
goto main
Emergency_Stop:
PortB.3 = 0
sleep
end

In the example above ASM interrupts will shut the motor off right now, PBP might have you wait 59 seconds
