/**
* Endstop Interrupts
*
* Without endstop interrupts the endstop pins must be polled continually in
* the stepper-ISR via endstops.update(), most of the time finding no change.
* With this feature endstops.update() is called only when we know that at
* least one endstop has changed state, saving valuable CPU cycles.
*
* This feature only works when all used endstop pins can generate an 'external interrupt'.
*
* Test whether pins issue interrupts on your board by flashing 'pin_interrupt_test.ino'.
* (Located in Marlin/buildroot/share/pin_interrupt_test/pin_interrupt_test.ino)
