You could be right. Depends on the IR pulses coming in. Some
remote controls use just a few microseconds for each pulse (to
get more range) but have quite a long time between pulses, perhaps
100us. The only necessary function of the ISR is to capture the edge
and toggle the trigger polarity for the next one. The data bit itself
can be determined and worked on outside the ISR. Personally I
prefer to have the ISR over and done with just to keep things tidy
