- *  Endstop interrupts
+ * Endstop Interrupts
- *  Without endstop interrups the stepper-ISR must always test all endstops when interested in their states (endstops.update()).
- *  Most time the test will result in finding out nothing has changed.
- *  With endstop interrupts endstops.update() is called only when we know that at least one endstop has changed its state.
  *
- *  This can work only if all __used__ endstop pins can provide ether an 'external interrupt' or a 'pin change interrupt'.
+ * Without endstop interrupts the endstop pins must be polled continually in
- *  You can find out about pins issuing interrupts by running 'pin_interrupt_test.ino' (Marlin\buildroot\share\pin_interrupt_test\pin_interrupt_test.ino)

+ * With this feature endstops.update() is called only when we know that at
