When it goes LOW, the interrupts cease. recipes for easy bake ovens

"WebI got 8 ns on both the rising and falling edges. If using the PORT instruction to set and clear bits instead of the much slower digitalWrite() instruction, the highest frequency I got by toggling a pin high and low was 2.666 Mhz. This is slowed down by the excessive time the arduino takes to pass execution back to the top of the Loop() marker. " - Rising falling change arduino
