End stops interrupt-capable?

I see this was asked once before and not answered. Are the end-stop pins interrupt-capable? I'd like to turn off polling if I can.

the marlin firmware has not enable the end-stop pins interrupt-capable by default as shown in configuration.h //#define ENDSTOP_INTERRUPTS_FEATURE

the end-stop pins are been read from the stepper motor interrupt function every time, so no need to set the end-stop pins as interrupt-capable.
