Instant Interrupts - Revisited

[sayzer]

Hi Sayzer,

For 14-bit chips,
It takes 1 instruction cycle to disable the interrupt and depending on what bank it's in at the time, it may take 1 or 2 instructions to change to the correct bank before disabling.

So @ 4mhz, it could take from 1 to 3 uS.

On 18F's, it's always just 1 instruction.

I assume your answer would be the same for other sources of interrupt (other then TMR0).
In any case, 3 uS is more then good enough for my case.

Thanks very much DT.
