  24. * Endstop Interrupts
  25. *
  26. * Without endstop interrupts the endstop pins must be polled continually in
  27. * the temperature-ISR via endstops.update(), most of the time finding no change.
  28. * With this feature endstops.update() is called only when we know that at
  29. * least one endstop has changed state, saving valuable CPU cycles.
  30. *
  31. * This feature only works when all used endstop pins can generate an 'external interrupt'.
  32. *
  33. * Test whether pins issue interrupts on your board by flashing 'pin_interrupt_test.ino'.
  34. * (Located in Marlin/buildroot/share/pin_interrupt_test/pin_interrupt_test.ino)
