Incredibly unlikely. Even if the processor is running at 20MHz (this is on the slow side, I'm sure its clock is more like 100MHz?), That's 50ns per clock cycle. And let's assume for fun that it only triggers on up or down edges, not both, that's 100ns per instruction. This is absolute worst case scenario. No way.
